Design of Spoof Surface Plasmon Polaritons Based Transmission Line at Terahertz Frequency

In this paper, we report a plasmonic metamaterial, i.e., spoof surface plasmon polaritons based back to back broadband transition at terahertz frequency. Also we have designed another structure using a unit cell that is made up of by combining three SSPP strip together. This structure shows a way to realize stopband within the operating frequency of spoof surface plasmon polaritons. Using the new type of unit cell disturbs the surface impedance matching and thus gives band stop in the transmission spectrum of SSPP. The first design of transition has reflection coefficient less than −10 dB and transmission loss is less than 5 dB in 0.1–0.8 THz range of frequency. The second designed structure shows strop band from 0.569 to 0.6124 THz and band pass is maintained from 0.1 to 0.569 THz and from 0.6124 to 0.6516 THz. Reflection coefficients in the band-pass region is less than −10 dB and transmission loss is less than 8 dB while in the band stop region reflection coefficient is −3 dB and transmission coefficient is −24 dB has been obtained. Such type structures will show promising application in plasmonic device and systems.

Application of the Fractal Defected Ground Structure in Design of the Bandpass Filter

The design of planar filter using stepped impedance type distributed synthesis has been proposed for 8.6–9.5 GHz frequency band. To improve the return loss characteristics, instead of using traditional defected ground structure (DGS), the combination of fractal geometry and DGS, known as ‘fractal DGS’ has been embedded in the ground plane of the filter. The filter using fractal geometry gives 65% better return loss as compared to filter without DGS. Three laboratory prototypes (without DGS, first iteration DGS and second iteration DGS) have been developed to validate the simulated and measured results.

Lightweight Effective Encryption Algorithm for Securing Data in Cloud Computing

Communication in the environment of cloud computing is implemented through the Internet and its backbone. Some issues of network security in the cloud environment are caused by its essential characteristics such as resource pooling, virtualized nature, elasticity, and other measured services. Though many algorithms have been used to secure the data communication in the cloud environment, some problems in the use of such algorithms still exist. Some of such problems are the mathematical complexity, key and security weakness, time complexity, and slow performance. In this paper, an algorithm called hyper data encryption (HDE) is proposed to combine the symmetric ciphers, secret sharing, and Diffie–Hellman key exchange concepts in order to enhance the security and solve the mentioned problems. Performance analysis is conducted in terms of key-space analysis, key sensitivity analysis, correlation analysis, information entropy analysis, time complexity, and execution time. The results show that the proposed algorithm is better in a cloud environment, which can provide strong security and high performance.

Internet of Things for Irrigation Monitoring and Controlling

The three things that the world runs on are water, wheel, and fire. Agriculture is largely based on water, its proper usage, storage, and management. This is a very key issue. With the advent of technology, manual systems evolved from being mechanized to being automatic and recently to being smart. The technology wave of Internet of Things can further ease the tedious task of watering and irrigating the fields, especially in the water scarce regions as well as in situations where fields are far away from residential areas. Also it saves the excess use of water for any crop. Erratic climate behavior in the Indian subcontinent in the last few years has led to extreme water scarcity in many regions. This paper proposes an irrigation monitoring and controlling system based on Wireless Sensor Network (WSN) and Internet of Things. The WSN remotely collects the data from the fields and transfers it to the cloud. The wireless sensor network uses two sensors: DHT and soil moisture sensor. A management server accesses the information over the cloud, a graphics user interface processes it and generates a feedback. This feedback is based on a user-selected crop name (stored in database) in the GUI. The information is sent over the cloud via IoT gateway. In this work, the hotspot from the mobile phone is used as an IoT gateway. The ESP8266-12E is used as controller as well as a Wi-Fi module. The feedback device is a 12 V DC pump. Whenever the soil moisture level senses dry soil (0-min %), the management system will generate a feedback signal to switch on the pump.

Hostel Rooms Power Management and Monitoring Using Internet of Things

Power saving is the important issue nowadays, and it is more critical in hostels because of some irresponsible students who leave the room without switching OFF the tubes lights and fans. So, for controlling this wastage of electricity in hostels, we have tried here to develop this system that helps in monitoring and managing the electrical power requirement. In this system, IR sensors sensed the presence of students in the room with the help of counter. When it counts one, it means students enters the room, this counter increases and so on. When the student leaves the room, it decreases the count and when it reaches up to zero, this indicates that no one is present in the room. At this time, after few seconds, the switches will automatically turn OFF, if it is ON, and this information will be sent to the server/cloud where the authorized person can see or watch all the activities in the room. Here, we need only Internet for watching the online process. This will be in the form of notification where it will show the room number, OFF time. The other feature of this system is, when such notifications will be seen on the screen, one SMS will be sent to the student about Rs. 100/- penalty or punishment. Internet of Things plays a vital role in this system. This promotes students to become responsible about careful utilization of electricity.

Analysis of Probabilistic Models for Influence Ranking in Social Networks

Influence is a phenomenon occurring in every social network. Network science literature on Influence ranking focuses on investigation and design of computational models for ranking of nodes by their influence and mapping the spread of their influence in the network. In addition to this contemporary literature seeks efficient and scalable influence ranking techniques that could be suitable for application on massive social networks. For this purpose joint and conditional probabilistic models could be a way forward as these models can be trained on data rapidly making them ideal for deployment on massive social networks. However identification of suitable predictors that may have a correlation with influence plays a major role in deciding the successful outcome for these models. The present investigation proceeds with the intuition that interaction is positively correlated with influence. Furthermore, through extensive experimentation it identifies a joint probabilistic model and trains it on interaction characteristics on nodes of a social network for influence ranking. A qualitative analysis of these models is presented to highlight its suitability.

Thus it guarantees service continuity, optimum network selection, user mobility and integration of new applications and resources. Integration of various wireless technologies in heterogeneous environment offers best service to every application. However, an automatic interface selection and user preferences based on quality of service parameters such as available resources, bandwidth, network delay or speed, security, and power consumption is desired. Hence network selection scheme explicitly based on user preferences and available resources is required.

Performance of Internal Cluster Validations Measures For Evolutionary Clustering

Clustering is an NP-hard grouping problem and thus there are advantages of using a metaheuristic (swarm intelligence) strategy to find the near global optimal solution to it. To effectively guide the agents of the swarm in the metaheuristic strategy, a suitable cost function is needed for successful outcome. The current inquiry focuses on the use of internal validation criteria as cost functions as they achieve the dual goals of clustering which are compactness and separation. Out of the multiple internal validation criteria included in the literature, two are identified for this purpose, viz. BetaCV and Dunn index. These were used as cost functions of the swarm optimizer metaheuristic (PSO-BCV and PSO-Dunn). To demonstrate the validity of the proposed technique, it was compared with other metaheuristics differential evolution as well as the traditional swarm optimizer based on distance-based criteria (PSO). The analysis of the results obtained on clustering benchmark datasets highlighted the suitability of this approach.

A Proposed Architecture for Cold Start Recommender by Clustering Contextual Data and Social Network Data

Recommender Systems (RS) help users in selecting the apt items based on their taste from a pool of items. These systems are able to do a proper recommendation with the aid of Machine Learning algorithms. The context of a user plays an important role in recommending relevant and important product/item to a user. Social media networks are useful knowledge sources to elicit more ratings from new users than state-of-art active Learning strategies. If we are designing an RS for users whose tastes differ according to the current context (e.g., feeling), we can collect contextual data and social media information so that we will be able to recommend the right product or item. We can do this recommendation by using cross-domain RS, Selective Context Acquisition, and Implicit Feedback. This paper provides insights based on the state-of-the-art contextual data and social media environments in providing the cold-start recommendations and also propose the architecture for recommending the items to solve the cold-start issue.

Unsupervised Feature Selection Using Correlation Score

Data of huge dimensionality is generated because of wide application of technologies. Using this data for the very purpose of decision-making is greatly affected because of the curse of dimensionality as selection of all features will lead to overfitting and ignoring the relevant ones can lead to information loss. Feature selection algorithms help to overcome this problem by identifying the subset of original features by retaining relevant features and by removing the redundant ones. This paper aims to evaluate and analyze some of the most popular feature selection algorithms using different benchmarked datasets. Relief, ReliefF, and Random Forest algorithms are evaluated and analyzed in the form of combinations of different rankers and classifiers. It is observed empirically that the accuracy of the ranker and classifier varies from dataset to dataset. This paper introduces the concept of applying multivariate correlation analysis (MCA) for feature selection. From results, it can be inferred that MCA exhibits better performance over the legacy-based feature selection algorithms.

Multi-constraint QoS Disjoint Multipath Routing in SDN

Efficient path computation that sustains varying quality of service requirements is a key networking concern. Even though modern networks turned to multipath routing schemes as a first step in this path, existing solutions still resulted in sub-flows being directed to the same paths. Moreover, maintaining the quality of service subject to multiple criterions while selecting the paths and handling connection requests dynamically has proved to be challenging tasks. Addressing all these issues requires a centralized, real-time- and fine-grained control of the network facilitated by Software Defined Networks (SDN) that have emerged as a revolutionary networking paradigm. In this paper, we deal with the former issue by computing k-max min disjoint paths and for the latter we use an analytic hierarchy process. The proposed solution combines the two approaches for deployment in an SDN environment.

Performance Analysis of Trust-Based Routing Protocol for MANET

Mobile Ad hoc network (MANET) is a self-motivated network. Nodes are freely moved anywhere inside the network. They can enter and depart the network at any instance. Due to loss of infrastructure in the network frequent link failures occurred. So the special classes of routing protocols are taken into account for reducing the link failures. Categories of protocols are Reactive, Proactive, and Hybrid. This reactive protocol reduces the routing overhead via sending the routing packets on every occasion there is want of communication. This paper mainly focused on the reactive protocols such as AODV, DSR, and AOMDV. Proposed work utilizes trust concept for finding the reliable route. In this work, we implemented Secure Routing Protocol which establishes a secure path between the nodes, totally based on the node trustworthiness. Based on the nodes past experience we calculate the nodes present trust value and finds the better route for data transmission. Proposed method improves the packet delivery ratio and throughput.

Unconventional Prediction Algorithm for Quick Route Convergence and Stability in MANET

Mobile Ad hoc Network (MANET) is infrastructureless network. Data between source and destination can be communicated through intermediate nodes. Nodes can move randomly and there is no central administration in ad hoc networking. Connectivity with corresponding nodes can be lost due to high mobility, battery power consumption, traffic, and node depletion. This results in repeated route failure. This intrudes the node association and degrades the network’s ability to offer the services to its colleague nodes. This makes route maintenance difficult, reduces the stability of the network, and hampers the flow of data. Information related to the route collapse cause can be used to improve the stability of the route. On this basis, Advance AODV (A-AODV) is proposed based on unconventional prediction algorithms without and with fuzzy logic to converge the route quickly for continuos data transmission. In this paper, the modifications have been made to the Ad hoc on-demand distance vector (AODV) route maintenance mechanism. Simulations are performed on qualnet 5.0. This paper covers comparative performance analysis of AODV and A-AODV techniques in reference of mobility and traffic. The results illustrated that the route stability can be enhanced through fuzzy prediction algorithm.

Performance Analysis of SLM Technique for PAPR Reduction in OFDM Using QPSK Modulation

Multi-carrier communication is a backbone of fourth-generation (4G) mobile communication due to high-data-rate capability. This multi-carrier communication is facilitated using orthogonal frequency-division multiplexing (OFDM). But high peak-to-average power ratio (PAPR) is a serious problem present in OFDM. High PAPR causes huge battery power consumption. To reduce PAPR, selected mapping (SLM) is one of the good technique from the set of scrambling methods. The performance of SLM technique for QPSK-modulated data with phase offsets of π/4, π/2, and 3π/2 using N = 64, 128, 512, 1024, and 2048 number of subcarriers in MATLAB environment is presented in this article. PAPR results of original OFDM and OFDM with SLM technique are plotted and also presented in tabular form for comparison. We have also investigated the computational complexity of SLM scrambler and descrambler block using Freescale StarCore SC140 architecture simulator.

Spatial Modulation Technique: Achievements and Challenges

Multiple antenna techniques are becoming one of the key technologies used for wireless communications these days. They trade-off higher data rates and superior error performance for increased complexity and cost. Spatial Modulation (SM) is a transmission technique using MIMO system to offer low-system complexity, improved data rate and better error performance in correlated channel environments. It exploits the properties of randomness and uniqueness of the wireless communication channel. This is done by using a coding method to establish a one is to one mapping of the transmitted information bits along with spatial positions of the transmitting antennas which are arranged in an array. The transmitted signal and the transmitting antenna number are estimated using this information for de-mapping the information block. This avoids Inter-channel Interference though a high spectral efficiency is maintained. This paper outlines the research achievements along with challenging research issues of this transmission technique.

A Novel Cluster Based Algorithm for Outlier Detection

Nowadays an important issue as well as challenge in data mining is obviously is outlier detection. Outlier detection has been used in many areas such as Fraud detection, Intrusion detection, Health care, Fault detection, etc., where detection of outliers is based on the different characteristics of data or datasets. In this current age of ‘Information Technology’, large numbers of processes are obtainable in the domain of data mining to discover the outliers by successfully creating the clusters and after that detecting the outliers from these created clusters. In data mining, cluster methods are highly essential and have been applied from micro- to macro-applications. Basically clusters are a pool of similar data objects put together grounded on the attributes and district features they have. Specifically outlier detection is used to recognize and exclude inconsistency from the available data sets. In the presented work an algorithm has been suggested which is based on clustering approach to the given data sets. The proposed algorithm efficiently detects outliers inside the clusters by using clustering algorithm and weight based approach.

Study and Effect of Architecture Deployed in BPO on Screen Recording Compliance for In-Centre Versus at-Home Agents

In business process outsourcing (BPO), Voice and Screen recording systems are deployed. Deploying these systems addresses the varied BPO needs such as compliance, quality management, improving customer experience, and dispute resolution. As per the architecture, recording systems record the agent and the customer voice. In addition, they screen capture the transactions carried out by an associate on his desktop—while handling the customer. The associate can be either physically on the BPO premises connected to the LAN (in-centre) or work from home (WFM) which allows to work at-home in any country. The main purpose of this study is to compare the recording effectiveness between associates operating in the contact centre premises (in-centre) verus associates working from home. The experiments show that there is a difference in the percentage of recordings achieved for in-centre associates verus the recordings carried out for work-from-home associates. The results clearly point out the need to bring about architectural changes to improve the effectiveness in the recordings at both types of working places. This paper also undertakes the experiment to verify if rebooting or restarting a user desktop at the end of each shift can impact recording percentages in a positive manner.

Document Theme Extraction Using Named-Entity Recognition

The text mining can be implemented by term analysis of word or phrase. This term which describes the concepts of particular sentence is use to define the document theme. The new context-based mining technique is introduced which uses the concept-based mining model to analyze the terms present in sentence, document, and corpus levels. We find the theme of document like organization, medical, entertainment, sport, and so on. Context-based mining apply on statistical data as well as real-time data like Export data from Wikipedia. The theme of document is extracted by using Natural Language processing (NLP) for communication between computer and human languages and name entity recognition (NER) algorithm for identification of entity, entity chunking, and entity extraction. It used to get name entity in text such as person name, organization name, specific locations, time expressions, percentages quantities and so on. NLP and NER are used in context-based mining for finding name of entity and their relationship. Context Vector containing set of documents is used to extract the context of the document. Finally K-Mean algorithm is used for clustering to find inherent groupings of the text documents, then set of clusters are generated where each cluster exhibit high intra cluster similarity and low inter cluster similarity. The text document clustering is used to separate documents into groups or clusters based on their similarity so all groups define the distinct topics.

Statistical Characterization of an Underwater Channel in a Tropical Shallow Freshwater Lake System

Underwater acoustics has made significant strides over the last century, which finds applications over a wide range from basic bathymetry study to high-end research extensions. The acoustic propagation in underwater is typically governed by physical properties of the underwater channel, such as temperature, pressure, and salinity. The seasonal fluctuations in the physical properties of the tropical region manifest as thermal stratification. The random thermal stratification has a significant impact on the Sound Speed Profile (SSP), thereby distorting the received echoes from the surface and the bottom. The site-specific behavior in the tropical region makes it an interesting research problem to investigate the correlation of the surface parameters like temperature with the surface and bottom reflection due to variations in the SSP. In this work, we attempt to present underwater channel characteristics of the tropical freshwater lake system at Khadakwasla (18.43° N, 73.76° E), located in the municipal limits of Pune city in India. The temperature gradient along the water column is computed using the one-dimensional Freshwater Lake Model (FLake) to derive the SSP using Medwin relation. The statistical analysis of the sound speed fluctuations resulted due to seasonal variation in the water temperature is presented using the Kolmogorov–Smirnov (KS) Goodness-of-Fit test is used to find a close Probability Density Function (pdf) match for the surface and the bottom path impulse response. The results indicate a good match of the surface and bottom path impulse response with Weibull distribution with a high confidence level. Such characterization can facilitate the design of adaptive algorithms to minimize the underwater channel impact based on a precise estimate of the channel impulse response.

Nonuniform Frequency Sampling Approach to FIR Filter Design

This paper investigates the new approach to FIR filter design based on nonuniform frequency sampling. This method generates the nonuniform samples in passband and stopband separately using Gaussian function. For the generated nonuniform sample, the desired frequency response values are generated using ideal filter characteristics. Then, taking its nonuniform IDFT gives the required filter coefficients. The proposed method is compared with existing methods like uniform frequency sampling and optimal filter design method and results show that the investigated approach has a better advantage over uniform frequency sampling and Parks–McClellan method with regard to the frequency response of designed filter.

The electroencephalograph (EEG) signals are most widely used for identification of neurological diseases like epilepsy, Alzheimer’s, and other brain diseases. Detection of epileptic activity requires a detailed analysis of the entire length of the EEG data. In this paper, we proposed an automated detection of epileptic seizure using energy distribution of wavelet coefficient in each sub-band frequencies of the EEG signals. The performance of the proposed method is investigated using signals obtained from public EEG database at the University Hospital Bonn, Germany. Initially, the EEG signals are de-noised and decomposed into sub-bands using discrete wavelet transform (DWT), Then wavelet energy distribution in each sub-band is calculated and used as a feature set. Finally, artificial neural network (ANN) used to classify the feature set with ANN. The method was tested on EEG data sets obtained from that belongs to three subject groups: (a) healthy, (b) seizure-free interval, and (c) epileptic syndrome during a seizure. The test result shows that the proposed method for detecting epileptic seizure can achieve an overall classification accuracy of 95%. The proposed method can be used efficiently for recognition of epileptic seizures.

Comparative Analysis of ICA, PCA-Based EASI and Wavelet-Based Unsupervised Denoising for EEG Signals

Electroencephalography (EEG) can be used to study various brain activities related to human responses and disorders. EEG signal is prone to noises which are caused due to eye movements, power-line interference, muscle movements, etc. Therefore, to obtain refined EEG signals for further processing, it should be denoised. There are several methods by which EEG signals can be denoised, among which we have used Independent Component Analysis (ICA), Principal Component Analysis (PCA)-based Equivariant Adaptive Separation by Independence (EASI), and Wavelet-based unsupervised denoising methods. The performance of these methods is compared using Signal-to-Noise Ratio (SNR) and Percentage Root-mean-square Difference (PRD).

Analyzing Effect of Meditation Using Higher Order Crossings and Functional Connectivity

People are experiencing difficulties in adapting to the rapid changes in work and social fabric due to the evolution of advanced technologies in everyday life. Health and well-being of an individual in the existing world is important for proper living. Meditation improves the adaptability of an individual to live a healthy and social life. To verify this, an experiment is designed with the simple meditation practice called Focused Attention for 8 weeks. The brain activity is recorded of 11 subjects using EMOTIV EPOC+ EEG device before (pre-meditation) and after (post-meditation) meditation. Features called Higher Order Crossings and Functional Connectivity are used to analyze the effect of meditation. The results indicated a decrease in HOC values for frontal, parietal, and occipital lobes and increase in HOC of temporal lobe. The interhemispheric connectivity increased after meditation practice.

The Detrended Fluctuation Analysis of EEG Signals: A Meditation-Based Study

The Detrended Fluctuation Analysis is a widely used method for analysis of non-stationary time series which has been applied to EEG signals. The Detrended Fluctuation Analysis (DFA) of the EEG signals in pre- and post-meditation (mindfulness) intervention are compared. It is observed that the EEG data obtained from 8 subjects out of total 11 subjects shows reduction in the DFA values. The reduction in DFA values represents the lower intrinsic fluctuations in the EEG time series, which is a measure of better (higher) complexity of these vital rhythms. The reduced DFA values after 8 weeks of Focused Attention (mindfulness) meditation practice in more number of subjects, indicates that the meditation practice enhances the ability to handle complexity. The reduced DFA values indicate improved neuronal functioning of these subjects.

Convex Optimization-Based Filter Bank Design for Contact Lens Detection

We have designed a novel convex optimization-based filter bank (FB), which minimizes the frequency band errors and optimizes time–frequency localization at the same time. The designed FB is regular and satisfies the constraint of perfect reconstruction (PR). In convex optimization, we have optimized quadratic constrained quadratic programs by transforming it into a semidefinite program. We have also compared the frequency band errors and time–frequency localization of proposed FB with existing FB. We have used this FB for designing a new contact lens detection (CLD) system. The IIITD database has been used for this purpose. The results have been expressed in terms of correct classification rate (CCR). The superiority of the designed FB has been shown by comparing the results with other existing CLD systems. The newly designed FB can also be effectively used for various signal processing applications.

EEG Waveform Classification Using Transform Domain Features and SVM

Electroencephalogram (EEG) waveforms are fluctuations in brain-recorded utilizing anodes set on the scalp. Albeit a few strategies for the evaluation of working of brain, for example, MEG, PET, CT scan, and MRI have been presented, the EEG waveform is as yet an important biological signal for checking the brain signal variations because of its moderately ease and being helpful for the patient. We have presented an approach to classify the EEG waveforms into two classes, viz. epileptic and normal. The algorithm fuses the features extracted using discrete wavelet transform, discrete cosine transform, and stationary wavelet transform. The fused features are subjected to support vector machine (SVM) classifier.

Colour-Adaptive Digital Image Watermarking Technique

Copyright protection and owner authentication have become necessary due to the circulation of large number of documents, images, audios, and videos through the internet. Manipulations and duplications in multimedia files and documents are very easy due to advancement in the signal and image processing algorithms. Therefore, it is very much important to devise watermarking techniques that are robust against geometrical distortions and collision attacks. In this paper, we proposed an adaptive digital image watermarking technique through colour features and Arnold transform in wavelet domain. An attempt has been made to adaptively transform the watermark image into a set of textures that visually match the colour of the input host image since colour features are invariant with respect to translation and rotation of the image. We first separate the three colours R, G, and B of the host and watermark image. Next, we decomposed the separated images using wavelet transform into sub-bands. Finally, low-frequency sub-band of the watermark image is embedded into low-frequency sub-band of the host image using Arnold transform. Experimental results on multiple host images and under various attacks using PSNR and correlation coefficient, clearly demonstrates that the proposed algorithm is robust and can be applied in colour image watermarking.

Improved Version of Tone-Mapped Quality Index

High Dynamic Range (HDR) images were evolved to display smallest details of the captured image with high standards. To display HDR images on Low Dynamic Range (LDR) monitors compression is required, which is done by Tone Mapping Operators (TMOs). Recently, there are a lot of tone mapping algorithms that are available in market. Different TMO creates images with different quality. To measure the quality of such images Tone-Mapped Quality Index was proposed (TMQI). TMQI mainly depends on the two parameters. The first is structural fidelity (SF) which is very similar to structural similarity and the second, is statistical naturalness (SN). The limitation of TMQI-1 is some parameter is image independent described in below sections so, improved model TMQI-2 is proposed in this paper. In order to further improve the quality of image, iterative optimization algorithm is used. Our experimental results show that TMQI-2 is better than earlier TMQI. Further, iterative optimization increases the overall quality of image.

Robust Exemplar-Based Image and Video Inpainting for Object Removal and Region Filling

Inpainting is an art that restores old and damage image. Exemplar-based inpainting uses the patch-based approach. It uses patches to fill the target region of the image. Also, it uses simultaneously the texture synthesis and structural propagation. But after some iteration, the dropping effect of confidence term occurs in this method. The robust exemplar-based method avoids dropping effect by using robust priority function. The proposed video inpainting method is based on the robust exemplar-based inpainting algorithm using region segmentation. Our algorithm uses a robust priority function to avoid dropping effect and region segmentation to determine the adaptive patch size and reduced search region. The experimental results show the effectiveness of our method.

Comparative Analysis for Steganographic LSB Variants

Combining the best features of steganography and cryptography is the trending concept which is being followed for the purpose of information security. Hence, this combination is making the data more powerful and secure against the prevailing security attacks and breaches. This paper represents the implementation of this combination on the two LSB variants, namely sequential LSB and randomized LSB. A comparison among the two approaches is carried out by adding a secret text into a video cover file. The concept of chaotic sequence has been used as the security approach that converts the secret data into random bits pattern. The proposed work uses the traditional LSB approach as basic steganographic model. The inference on the basis of parameters concludes that the randomized LSB shows better results than the sequential LSB scheme.

Integrating Machine Learning Tool to Improve DSS Design

This paper describes how a machine learning tool can be applied to decision support system. We have used fuzzy logic to enhance performance of DSS. Further, system developed is implemented in agriculture domain for selection of suitable crop. Selection of crop is complex process as it involves number of parameters where uncertainty is more common for example rainfall, suitable seeds, fertilizers, number of soil parameters, temperature, air quality, humidity, and so on. The present work focuses on soil parameters and few other parameters which support proper growth of crops. Fuzzy logic is applied to those parameters for handling data uncertainty. This is an attempt to suggest proper decision and reduce the burden by designing new DSS. Experimental set-up shows increased crop production up to 10–12%.

Face Recognition Using Eigenfaces

In this paper, we propose a PCA-based face recognition system implemented using the concept of neural networks. This system has three stages, viz. pre processing, PCA and face recognition. The first stage, preprocessing performs head orientation and normalization. The aspects that matter for the identification process are ploughed out using Principal Component Analysis (PCA). Using the initial set of facial images, we calculate the corresponding eigenfaces. Every new face is presented into the face space and is characterized by weighted-sum of corresponding eigenfaces that is used to recognize a face. To implement this face recognition system, we have created a database of faces with the help of neural networks and we have built one separate network per person. We obtain a descriptor by projecting a face as input on the eigenface space, then that descriptor is fed as input to the pre-trained network of each object. We select and report that which has the max output provided it passes the threshold already defined for the recognition system. Testing of the algorithm is done on ORL Database.

Multi-focal Image Fusion with Convolutional Sparse Representation and Stationary Wavelet Transform

This paper illustrates a completely unique technique of multi-focus image fusion involving Stationary Wavelet Transform (SWT) and Convolutional Sparse Representation (CSR). Sparse-based fusion strategies do not retain information representation and cannot tolerate minor mistakes in registration. The SWT method does not have these issues. Multi-focus image fusion is the fusion of different parts of digital images, representing the common scene, in order to produce an image with everything in Focus, i.e., without the blur effect. Camera processors cannot fuse images by themselves. Thus, experts have to employ image editing methods to obtain clear photographs. The scheme stated in this paper uses SWT to distinguish focus levels accurately. The results suggest that the strategy is successful in ways comparable in terms of visual quality and clarity.

Fuzzy Deep Learning for Diabetes Detection

The use of science for the betterment of society is the main cause for research for years. That is the reason the framework of diabetes diagnosis is always changing with new dimensions. The new and advance algorithms on the horizons are tried in hope of getting better accuracy and speed. Apart from normal algorithms researchers have tried the possible hybrid combinations. In recent times, the Convolution Neural Network (CNN) has outperformed most of the application areas of traditional prediction algorithms. Here is an attempt to use the deep convolutional neural network for diagnosis of diabetes. This work has two major contributions, first is the application of CNN for diabetes detection and second is data fuzzification in matrix form to suit needs of CNN. In the experiments, the comparison is made between classical NN and CNN for diabetes detection. Results prove that fuzzification of data significantly improves the accuracy of CNN and CNN outperforms classical NN.

Classification of Magnetic Resonance Brain Images Using Local Binary Pattern as Input to Minimal Complexity Machine

Magnetic Resonance Imaging (MRI) is a powerful visualization tool that is extensively used in medical laboratories to capture images of internal anatomy of human body. Classification of MRI brain images into tumorous and non-tumorous image is a critical and time-consuming task for the radiologist. Correct and computerized classification of MRI brain images is very important for their investigation and analysis. In this paper, we have proposed to use binary patterns (LBP) as features to classify MRI brain images into tumorous and non-tumorous. The LBP computes the relationship between central pixel and neighboring pixels of the 3 × 3 window and assigns a label to each window. The histogram of these labels is then used as a feature vector that is fed into the classification stage. The images are classified using Minimal complexity machine (MCM) algorithm. As compared to Support Vector Machine (SVM) algorithm, MCM performs better generalization and makes use of lesser number of support vectors. The performance analysis of the proposed techniques is done on the basis of accuracy calculated, and it is found that the classification rate is superior to other existing algorithms.

Underwater Image Colour Balance by Grey World Approach with Attenuation Map

Underwater images are degraded by attenuation of light in water. This attenuation depends upon wavelength and depth in water. One of the effects of degradation of image in water is absorption of colour giving greenish-blue hue to the image. Because of this colour fading of underwater images, colour correction is the first preprocessing step in underwater image processing. Many researchers attempted colour correction methods but most of it operates globally. Global colour correction methods give reddish effect to image. The method proposed in this paper used Grey World approach for colour correction, but it is modified using attenuation map. Use of attenuation map avoids saturation of colours and colour corrects only those pixels which are significantly attenuated. Results of the proposed method are compared with state-of-the-art methods by quality metrics mean square error, structural similarity index and entropy of image. It is seen that the proposed method in this paper gives better results than state-of-the-art methods.

Technique of Face Recognition Based on PCA with Eigen-Face Approach

PCA is utilized in the area of recognition of face, fingerprint, handprint, industrial robotics, and mobile robotics. In the face recognition, research shows that the success rate is not satisfactory for a variant of poses which have rotation gap of more than 30°. If there are lots of variations in lightning, expressions, and pose variation, then PCA results are not up to the mark in the existing algorithm. This problem is arising in mind. The objective of the present paper is to study and propose modified PCA and Eigen-face-based algorithm to improve result with the accuracy of face recognition. In this paper, we focus on the pose variations which have 30° range of pose in image.

Line Scratch Detection in Old Motion Picture

Detecting line scratch in motion is a tedious job because it requires spatial as well as temporal features needs to be extracted. Scratches are caused by abrasion of film material as it passes through projection mechanism. One main problem in this is false detection. Spatial algorithm is used to detect scratch inside the frame using frame-wise scratch detection and temporal algorithm is used for filtering false detection. Preprocessing is required to get fine results. Experiment result shows the detection of line scratches in motion picture.

Underwater Image Enhancement by Rayleigh Stretching with Adaptive Scale Parameter and Energy Correction

Attenuation of light in water causes degradation of underwater images. This attenuation is caused by water molecules, suspended particles, and dissolved chemical compounds in water. The attenuation includes scattering and absorption of light in water. Backward scattering and fading of color are two major sources of degradation of underwater images. This paper proposed a method of enhancement of underwater images by providing a solution for degradation because of backward scattering. The proposed method corrects the effect of backward scattering by enhancing contrast of the image by Rayleigh stretching of each color channel using maximum likelihood estimation of scale parameter. After contrast enhancement, loss of energy in the signal is corrected, that recovers information loss caused by contrast enhancement. The results of the proposed method are compared quantitatively with state-of-the-art methods by applying it to underwater dataset. Comparison is done with mean square error (MSE), Structural SIMilarity index (SSIM), and Average Information Entropy (AIE) quality metrics. It is seen that the proposed method in this paper produces best results when compared with state-of-the-art methods.

Medical and Color Image Compression with Fractal Quadtree with Huffman Coding for Different Threshold Values

Fractal Image Compression (FIC) is characterized by long encoding time and high Compression Ratio (CR). Further, as medical images being voluminous, a high CR is required to reduce the storage space. Fractal Image compression adopts affine transforms. In view of this, the present paper aims in providing an implementation of a hybrid approach by combining Quadtree fractal with Huffman coding with different threshold values and a comparative analysis of the different types of input images such as color as well as different modalities of medical images as MRI and X-ray to achieve high CR by still retaining the quality of the image. The implementation is carried out and results are obtained using MATLAB. The performance parameters as encoding time, compression ratio PSNR, and decoding time are compared. The results have shown that with an increase in threshold value, CR increases with a decrease in image quality for color as well as medical images.

A Novel Method to Detect Fovea from Color Fundus Images

The computer-aided diagnosis technology in retinal image analysis requires localization of different fundus structures. Efficient detection and localization of fovea are essential in the analysis of diabetic macular edema. This paper demonstrates a novel technique for detection of fovea from color fundus images based on image enhancement by adaptive manifold filter and further mathematical morphological operations for final foveal center localization. The major advantage of the proposed technique is that it does not need a spatial relationship of optic disc and vessels for the detection of fovea. It is robust to illumination changes and interference caused by retinal pathologies. Experiments show encouraging results that are analyzed on five publically available databases DRIVE, HEI-MED, DIARETDB1, HRF, and MESSIDOR with an accuracy of detection as 100%, 99.40%, 98.88%, 100%, and 98.66%, respectively. Comparative analysis of results indicates that the proposed method achieves better performance than other earlier methods present in the literature.

Gender Identification from Frontal Facial Images Using Multiresolution Statistical Descriptors

Gender identification is a significant task which is very useful in many computer applications like human–computer interaction, surveillance, demographic studies, and forensic studies. Being one of the most popular soft biometrics, gender information plays a vital role in improvement of the accuracy of biometric systems. In this paper, we have presented an approach based on multiresolution statistical descriptors derived from histogram of Discrete Wavelet Transform. First, the input facial image was enhanced by applying contrast limited adaptive histogram equalization. During feature extraction, multiresolution statistical descriptors were computed and fed into the Nearest Neighbor, Support Vector Machine, and Linear Discriminant Analysis classifiers respectively. We have achieved encouraging accuracy for gender identification on complex dataset of frontal facial images.

Captioning the Images: A Deep Analysis

Image captioning is one of the fundamental tasks in machine learning since the ability to generate text captions of an image can have a great impact by assisting us in day-to-day life. However, it is not just an object classification or recognition task, because the model must know the dependencies among the recognized objects and their attributes and encode that knowledge correctly in the caption using a natural language like English. Recently, the internet is overwhelmed with the huge amount of textual and visual data consisting of billions of unstructured images and videos. Meaningful captions will serve as useful keys for retrieval, creative searching, and powerful browsing of these images. In this paper, we present the goal of analysis and classification of the recent state-of-the-art in image captioning and discuss significant differences among them. We provide a comparative review of existing models, techniques with their advantages and disadvantages. Future directions in the field of automatic image caption generation are also explored.

Age-Type Identification and Recognition of Historical Kannada Handwritten Document Images Using HOG Feature Descriptors

Most of the historical Kannada handwritten documents are preserved in the manuscript preservation centre and archaeological departments. The historical Kannada handwritten documents are generally degraded in nature, due to this degradation, the documents are impossible to read and understand the contents. Hence, it is very much essential to restore by digitizing the historical Kannada handwritten documents and also recognize the originality of the dynasty to which it belongs. The main objective of the research work is to reconstruct, digitize and recognize the historical Kannada handwritten document images by applying image enhancement techniques and obtain the HOG feature descriptors using K-nearest neighbour (K-NN) and SVM classifiers. In this paper, we have considered historical Kannada handwritten document images of different dynasties based on their age-type; Vijayanagara dynasty (1460 AD), Mysore Wadiyar dynasty (1936 AD), Vijayanagara dynasty (1400 AD) and Hoysala dynasty (1340 AD) for experimentation. The average classification accuracy for different dynasties: in case of K-NN classifier is 92.3% and SVM classifier is 96.7%, It is observed that the SVM classifier has got a good classification performance comparatively K-NN classifier for Historical Kannada handwritten document images. The experimental outcomes are tested with manual results and other methods in the literature, which show the thoroughness of the proposed technique.

Image Inpainting for Hemorrhage Detection in Mass Screening of Diabetic Retinopathy

Diabetic retinopathy (DR) is one of the main causes of vision loss. The severity of DR can be analyzed using human retinal images (fundus image). Affected fundus image consists of hemorrhages, microaneurysms, and exudates along with blood vessels. In order to accurately detect the level of severity of the disease, the blood vessels are inpainted using fast marching method (FMM). The technique implemented in this paper involves image enhancement using green channel image and histogram equalization followed by mask generation and inpainting. The severity of the disease can be categorized accurately by inpainting the blood vessels using FMM. The proposed technique is tested using standard test databases HRF and DRIVE. The algorithm can be effectively used for mass screening of DR. This technique is a fundamental step in designing computer-aided diagnosis system for ophthalmic disorders.

Performance Analysis and Implementation of DES Algorithm and RSA Algorithm with Image and Audio Steganography Techniques

In today’s era, data security is an important concern. It is most demanding issue nowadays. It is essential for people using online banking, e-shopping, reservations, etc. The two major techniques that are used for secure communication are Cryptography and Steganography. Cryptographic algorithms scramble the data, so that the intruder will not be able to retrieve it; however, steganography covers that data in some cover file, so that the presence of communication is hidden. There are some techniques that integrate cryptography and steganography to provide multi-layer security. This paper shows the comparison of such two techniques. These are “RSA cryptography with image steganography and with audio steganography” and “DES cryptography with image steganography and with audio steganography”. Stimulated results have been presented using MATLAB software.

Content-Based Image Retrieval Using Color and Texture Features Through Ant Colony Optimization

Content-based image retrieval (CBIR) is retrieving relevant images from the large image database through visual characteristics. Each image in the database and query image is represented through feature vector derived from color and texture features in the image. These feature vectors are compared for relevance to obtain similar images in CBIR system. Therefore, length of the feature vector is very important in the CBIR system. Higher length of the feature vector increases number of comparison and in turn, increases the computational complexity, whereas lower length of the feature vector reduces comparison and complexity. In this paper, performance of the proposed CBIR system using color and texture feature extraction through histogram and Gabor wavelet transform, respectively, is presented. It is necessary to extract all the features of each image from image database and query images. These features are further presented for ant colony optimization to reduce the length of the feature vector. These final features are used in image retrieval process. Experiment results clearly show that the proposed CBIR system through ant colony optimization algorithm performance is better than other algorithms by 1.8% with respect to precision and recall. Also, the proposed algorithm clearly demonstrates the improvement by 10% on the precision and recall using only color and texture features. One of the biggest advantage and improvement was reduction in retrieval time in comparison with the other algorithms.
