| 摘 要： | 为了减少视频编码的运算量，对全零块判决进行了深入的研究，并结合图像的纹理信息和帧间编码模式给出了自适应的全零块判决阈值，以此为基础提出了EPZS（enhanced predictive zonal search）的改进算法。实验结果表明，改进的EPZS算法在较好地保持H.264/AVC原有编码算法图像质量的同时，减少了运算量，大幅度提高了编码速度。

| Abstract: | 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. |
