Stereo Sequence Coding Based on Segmentation

摘要

In this paper, we have discussed various disparity estimation(DE) algorithms. The segmentation-based DE algorithms can provide better performance, and the novel object-based arbitrary shape segmentation is the future developing direction. Meanwhile, a segmentation-based stereo image sequence coding scheme is proposed, which can achieve a higher compression ratio by efficiently exploiting the redundancy within stereo sequences. One image stream is independently coded by using MPEG-type or H.26x-type methods. Only a few reference image frames in the other image stream are coded by adopting the segmentation-based DE algorithms. Most of image frames in the second image stream are not coded and they are reconstructed at the decoder by a frame estimation and interpolation technique.
