Title: A study of very low bit rate video coding
Author: Wang, Naxin
Abstract: This work focuses on the low bit rate video coding used in video conferencing system. A simplified segmentation based coding approach is exponed to H 263 and MPEG-1 standards. This approach uses the motion information to separate the moving objects from the rest and segments the moving macroblocks into objects Based on the features of video conferencing sequence, the encoder is optimized so that more bits are spent on theses moving objects and the others are treated as background Therefore, it saves a lot of bits. The encoder can select the objects by their sizes or let the viewer select them. The quality of the output is fine by our observation.
