The recently developed video compression standard, H.264/AVC surpasses the performance of previous video standards, such as MPEG-2, MPEG-4(part2), and H.263 and is therefore expected to be selected as the video standard for most digital video applications. The widely distributed infrastructure, however, continues to use the previous standards. Heterogeneous video transcoding offers a significant key...
In this paper, we discuss methods to enable robust surveillance on compressed video. We show that if the particular surveillance algorithm that is likely to be run on the compressed video is known a priori, then steps can be taken during the encoding process to facilitate the performance of the algorithm. We show that by performing signal processing on the input video signal before it is encoded,...
Video transmission over wireless networks faces several challenges, such as time-varying error rate, bandwidth variation and limitation, battery power limitation. This in turn brings out the need for error resilient video transport, low power dissipation and high compression efficiency. Next generation wireless networks are likely to operate on internet technology combined with various access technologies...
