块分类的双向估计加权边信息生成算法
Block-classified side information generation algorithm with bidirectional motion estimation and weight decision
摘要
Abstract
In distributed video coding ( DVC) system, the side information ( SI) generation used motion estimation which brought an overlapped issue. This paper presented a block-classified side information generation algorithm which adopted an improved bidirectional motion estimation and weight decision. The pixel blocks were classified into two parts; the saving blocks and the moving blocks according to the correlation between the blocks in adjacent key frames. The saving blocks were retained directly. For the moving blocks, the matching blocks were found by an improved bidirectional motion estimation interpolation. Finally, generated the side information by using the weighted decision module. Simulation results show that the proposed algorithm can produce improvement in the quality of side information without increasing the complexity of the encoder.关键词
