In order to code and decode the stereo video sequences effectually and acquire excellent reconstructed images

a frame estimation and interpolation technique of stereo video sequences is presented in this paper. In stereo sequence coding

the left image stream is coded according to theMPEG-Ⅰ/Ⅱvideo coding standard. In the right image stream

only reference frames (I and P) are coded

the B frames in the right image stream are neither coded nor transmitted

they are acquired from the reference frames with the frame reconstruction and interpolation technique at the decoding end. The variable block segmentation is based on a multi-resolution quadtree-based motion segmentation. This paper also proposes a novel method to process the reconstruction of right B frame as matched-block and unmatched-block separately

the positions and content of these blocks are decided on the correlation between the blocks in right B frames and right I

P frames or left B frames. Anovel frame reconstruction and interpolation technique for overlapped blocks to avoid false matching and to fill the exposed regions correctly is also proposed in this paper. The simulate experiment results show that the average PSNR is about 1.25dB higher than the method mentioned in the refernce[1]

Which is based on fixed blocks

and the reconstructed frames have a much better presentation on viewing perception.
