%X In order to reduce the computation in video codec, this paper studied all-zero block decision is profoundly, and gave the adaptive threshod of all-zero block decision in combination with the texture informations of image and the mode of interframe coding. On the basis of this, proposed an improved EPZS algorithm. The simulation result shows that the proposed algorithm can highly speed up video coding while basically maintaining the quality of image.
