Direct Mode Coding for B Pictures using Virtual Reference Picture
The direct mode used in the bi-predictive pictures (B-pictures) can efficiently improve the coding performance of B pictures, because it has small overhead and obtains a predictiv...

Hash-Based Motion Modeling in Wyner-Ziv Video Coding
Generally, Distributed video coding (DVC) schemes perform motion estimation at the decoder side, without the current frame being available. In order to generate the side-informati...
