Abstract

Advancement in smart mobile phones and wireless networks technology have broaden capability of mobile phones rather than being limited for voice communication. Smart mobile devices are true multimedia devices proficient of directing, receiving, transforming, transmitting and presentation of data like image, audio, video, and text. These features facilitate high interactive learning system in mobile phones called m-learning. Many approaches have been proposed to improve the quality, as well as reduce the duration of learning videos due to the limited memory size of mobile phones. Moreover, the cameras used so far are high-definition standard cameras which are costly. Therefore, in this paper we propose to develop an android based mobile application which captures as well as stream lecture videos using mobile phone camera. Moreover, we have proposed a content analysis algorithm to reduce size of video frames as well as bandwidth requirement for transmission. We have evaluated our proposed algorithm for various dataset captured in different classroom scenarios. We have also tested our algorithm with the MPEG compression which achieves compression ratios more than 1,000 times to those of the MPEG compression.
