| Abstract: | We give the image organization optimization algorithm of improvement from the image of SIMD parallel operation, such as the idea of oriented object to lead into Parallel operation process that calculated SAD value. Frum the test result of moving forecast for many standards testing sequence , we know that in current most complex video coding H. 264/AVC, the implement of this algorithm can raise the coding speed of encoder obviously , and offer guarantee to realize the video communication of real time in narrow bandwidth. |
