Xiaowu Li · Jisuanji gongcheng · 2011
In accordance with the complexity of AVS-M motion search algorithm,according to the characteristics of its converting quantification,all-zero block judgment criterion is deduced and an AVS-M fast motion search algorithm based on all-zero block detection is proposed.The algorithm judges all-zero block when moving and searching,which saves a lot of time on moving search and converting quantification.Experimental results show that the computational capacity saved by the algorithm can amount to 77.4% at most,and the dropped level of Bits is larger than PSNR.The encoding speed of motion estimation can be effectively increased without the lower encoding performance.
