数字图像放大缩小及旋转计算组间方差和组内方差的时候调用了一个函数专门求阈值，可能这里的计算还是有一点问题。而且在我的函数里，要256次调用这个函数，又因为计算机是按字节处理数据的，因此写图像数据的时候要用每8个写到一个数组中，然后通过计算得到字节类型的值，这些都使得我的算法效率比较低，最后一个问题，我觉得如果使用位运算会快一些，但是前面的问题还没有想到比较好的解决方法。-Digital Image zoom and rotation calculation of variances and gr

Motion estimation is the process of determining motion vectors that describe the transformation from one 2D image to another usually from adjacent frames in a video sequence. It is an ill-posed problem as the motion is in three dimensions but the ima
