Overlapped block motion compensation for variable size blocks in the context of MCTF scalable video coders

摘要

Method for processing video frames, recording medium, and a computer system is disclosed. The current frame is divided into M blocks having at least two different sizes. M is at least 9. Each block of the current frame is classified as a motion block or blocks I-. The duplicate block motion compensation (OBMC) is performed for each block of M blocks in accordance with a predetermined scan order. OBMC blocks that are performed by the self-block represents. OBMC on the self block is carried out with respect to its neighboring blocks. Neighboring blocks are provided with a nearest neighbor block of the self block. Performing of OBMC on the self block comprising generating a weighting window for the self block and its neighboring blocks each. ; MCTF, motion compensation, I- block, a motion block, VSBM, a scalable video coder
