Joint audio-video processing of MPEG encoded sequences

The current research efforts in the field of video parsing and analysis are focused on the use of pictorial information, while neglecting an important supplementary source of content information such as the embedded audio or soundtrack. In contrast, we address the issue of scene change detection with the use of video and audio information. We also discuss how joint exploitation of audio and video can be thoroughly performed on MPEG encoded video sequences. First experimental results are presented and discussed.
