Region-based fractal coding of stereo video sequences with quadtree-based disparity compensation

In order to realize the efficient and economical transmission/storage of stereo video sequences and also the region-based functionality of MPEG-4, we propose a new stereo video sequences compression scheme which using fractal coding and encoding each region independently by a prior image segmentation map (alpha plane) which is exactly the same as in MPEG-4. We encode the first n frames of right video sequence as a "set" using the Circular Prediction Mapping (CPM) method and encoding the remaining frames using the Non Contractive Interframe Mapping (NCIM) method. The CPM and NCIM methods accomplish the motion estimation/compensation which can exploit the high temporal correlations between adjacent frames of right sequence, at the same time, we exploit the spatial correlations between the left and right frames by searching the similar blocks using the quadtree-based disparity estimation/compensation, the experimental results indicate we get high compression ratio and also good PSNR.
