摘要
着重讨论帧间预测码运动补偿算法,该算法可获得比一般的运动块匹配方法更大的峰值信噪比,该基于小波变换域的块搜索匹配算法,在运动比较平缓时能以很少的运算次数马上找到块匹配点;在运动非常激烈时,则首先采用小波变换,然后再用本方法进行块匹配搜索,可减少大量复杂的运算量。
In this paper we mainly talk about the calculation of motive video coding. This calculation can acquire more PSNR than the general motive block match.In the calculating way which based on the wavelet transformation area we can find the point of block match immediately with less times when slowly moving .If the movement is drastic, adopt the wavelet transformation first, then use this method to search block match, which can reduce a great deal of complicated calculating.
