Über dieses Buch

This book presents theoretical and practical aspects of the interaction between low and high level image processing. Multiresolution analysis owes its popularity mostly to wavelets and is widely used in a variety of applications. Low level image processing is important for the performance of many high level applications. The book includes examples from different research fields, i.e. video surveillance; biomedical applications (EMG and X-ray); improved communication, namely teleoperation, telemedicine, animation, augmented/virtual reality and robot vision; monitoring of the condition of ship systems and image quality control.

Chapter 3. Multiresolution Approaches in Image Processing

Abstract
This chapter explains a multiresolution approach to the image processing. Several transforms are mentioned, which can be used in the multiresolution approach. Wavelets are compared with Fourier transform, and short-term Fourier transform. Wavelet implementation issues are presented. Wavelet analysis is illustrated by an experimental example.

Chapter 4. Visual Quality Control

Abstract
Quality control is an interesting topic in signal processing. This chapter deals with quality control with a camera input to the algorithm. A literature overview is given. It is presented how the multiresolution can be used in this application. The last section explains how to use visualization techniques in dielectric material’s properties analysis.

Chapter 5. Possibilities for the Improvement of Human Work Conditions by Virtual/Augmented Reality

Abstract
This chapter deals with possibilities for the improvement of human work conditions and with the relaxation at remote and isolated work places (oil rigs, ships, spacecrafts, etc.). It is shown how cutting-edge visualization and communication techniques can improve safety and security. Furthermore, a multiresolution role is explained.

Chapter 6. Computer-Aided Diagnostics and Multiresolution Analysis Role in Medical Signal Processing

Abstract
Multiresolution role is considered for the application in computer-aided diagnostics. Two examples are shown, which are in the scope of our research group. The first example presents preliminary results in EMG analysis of brain signals obtained by experimenting with stutterers. The second example shows research results in diagnostics of occupational asbestosis. It was found how much levels of wavelet decomposition can be used without damage to the medical information in pulmonary X-ray images of the asbestos infected patients.

Chapter 7. Multiresolution Applications in Video Surveillance

Abstract
In this chapter, a multiresolution approach is solving several video surveillance issues is explained. Firstly, edge detection in robot vision is considered. Then, illumination variations problem is addressed with example in people motion detection. Camera jitter problem is addressed in the outdoor example. Removal of weather conditions is considered. Finally, an algorithm for data fusion is presented, which uses wavelet multiresolution approach in oil spill detection from the SAR images.

Chapter 8. Conclusions

Abstract
Area covered with this book includes several well-funded industries: the industry of medical electronics, the military industry and the entertainment industry. This chapter summarizes the conclusions from all chapters. General conclusion is the interaction between low-level vision applications and high-level vision applications, which are responsible for the final result of the system.
