Abstract： |
The invention relates to one visual frequency compression codes macro block coding mode selection method, which comprises the following steps: predicting move and processing rapid speed and lose estimation after exchange and volume during computation, processing exchange parameters as zero in speed estimation computation, establishing non-zero parameters sum, and number and journey sum and relation module defining one index function to meter non-zero parameter number and journey sum impact on speed with each real code for one block to update index list according to low pass filter according to speed and aberration estimation to process macro coding module selection. |
