Early DIRECT mode decision based on all-zero block and rate distortion cost for multiview video coding

摘要: The exhaustive variable-block-size mode decision can efficiently remove the redundancies among multiview videos, while it also leads to significant increase of computational complexity in video coding (MVC) encoder, and high encoding becomes a bottleneck for MVC encoder achieve real-time multimedia applications. To address this bottleneck, many fast methods have been proposed. However, most them are only suitable optimising odd views encoder. In study, based on property all-zero block rate distortion (RD) cost DIRECT as well correlations between current macroblock (MB) its spatial–temporal nearby MBs, an early method is proposed reducing MVC. Experimental results show that achieves 48.25 55.64% average time saving even views, respectively, whereas RD performance degradation quite acceptable. summary, reduces
