The so-called DIRECT coding mode plays an important role in the RD performance of predictive video coding such as the H.264/AVC and MPEG-4 standards because there is typically a large probability that the DIRECT mode is selected in B-slices by the rate-distortion optimization (RDO) process. Although the current H.264/AVC DIRECT coding procedure exploits the motion vectors (MV) obtained from the reference...
The Wyner-Ziv video coding (WZVC) efficiency is highly dependent on the quality of the side information (SI) created at the decoder, typically through motion compensated frame interpolation (MCFI) techniques. Since the decoder only has available some reference decoded frames, SI creation turns out to be a difficult problem in WZVC. In most the MCFI techniques available, the matching criterion used...
