Abstract: SAD (sum of absolute differences) is a technique for evaluating the similarity between two same size regions , and widely used in stereovision, optical flow, motion estimation and so on.
It is calculated by taking the absolute difference between each pixel in the original block and the corresponding pixel in the block being used for comparison. |
Absolute difference is the same as max(a, b) - min(a, b). How can you use this fact with the fact that the array is sorted? |
