| 摘 要： | 提出了一种称为准全搜索法的块匹配改进算法。该算法在传统全搜索法的基础上引入了差值块DCT系数为0的判断条件，在螺旋搜索的遍历过程中可以最快地搜索到满足条件的匹配块，在大大提高搜索速度地同时也保证了一定的搜索精度。

| Abstract: | In this paper, a quasi full search method for the improved motion estimation algorithm is proposed. The algorithm introduces the judgement condition for the zero DCT coefficients of the difference block into the traditional full search method. It can find the match block as soon as possible with considerable searching precision through the helix searching mode. |
