摘要
在分析了块匹配运动估值模型的基础上,指出处于块中央的象素点在块匹配时作用较小,因而提出了一种减少块匹配运算象素的方法。不仅如此,提出的方法可与任一基于减少匹配次数的快速算法相结合,从而得到各种混合型的块匹配快速算法。最后试验结果表明,提出的方法是有效的。
Based on an analysis to the model of block matching motion estimation,it is indicated that the pixels at the center of block contribue less in finding the best motion vector and therefore a method is proposed to reduce the number of pixels needed in the operation of block matching.The proposed method can be embedded in any algorithm which is based on limited search location. Experimental results show that the method is effective. [
