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 .
