A Fast Stereoscopic Frame Estimation and Interpolation Algorithm in Compressed Stereo Video Streams

摘要

A novel stereoscopic coding-decoding framework was proposed in this paper. The reference image stream of a stereoscopic sequence is independently coded by a conventional MPEG-type scheme at higher quality; only a few reference frames in target stream are coded and transmitted. The rest frames are 'skipped' and are reconstructed at the decoder using a Combine Stereoscopic Frame Estimation and Interpolation without search (CSFEI) technique proposed in this paper. In order to estimate the unfilled regions due to occlusion, a global solution based on a probability model is also proposed. Simulation results show that the CSFEI scheme can achieve a PSNR gain (about 2-3 dB) as compared to the block-based matching algorithm.
