AVS Quick Mode Selection Algorithm Based On Adaptive Threshold
In accordance with the complexity of AVS motion search and block mode selection algorithm,the paper poses a AVS quick mode selection algorithm based on premature termination norm and adaptive threshold.The algorithm can avoid much cost calculation of the useless macro block and save a lot of time on moving search and block mode selection in encoding process.Experimental results show that the computational capacity saved by the algorithm can amount to 78.6% at most,and the dropped level of Bits is larger than PSNR.The encoding speed can be effectively increased without the lower encoding performance.
