IMPROVED DISPARITY ESTIMATION ALGORITHM WITH MPEG-2S SCALABILITY FOR STEREOSCOPIC SEQUENCES

The disparity vectors are used for the reconstruction of the right ima ge sequence from the left one (vice versa) in a 3DTV transmission syst em. An improved matching algorithm for disparity compensated stereosco pic video coding is presented in this paper. The algorithm requires tr ansmitting the same amount of disparity data as the conventional block matching algorithm (BMA) while achieving much higher prediction accur acy by refinement scheme that captures the fine disparity variation be tween left and right image sequences.
