在运动估计中通过对多种块匹配算法进行实验,选择了一种可以满足系统要求的算法——新的三步搜索法。
Through testing many different Block Matching Algorithms in the motion estimation, the New Three Step Search Algorithm is chosen, which can fulfill the requirement of the system.
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。
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.
在H。 264的多宏块运动估计中,全搜索虽然能得到最佳的匹配,但在计算上却很繁琐,无法达到实时的要求。
In the multiblock motion estimation of H. 264 standant, although full search can obtain the best matching, it can't support the demand of real time because of its complexity computation.
