Hi guys!

I have to process an image where i need to know how many times a pixel has been overlapped. The image attached can be used as an example:

In the image the three patches (B1, B2, B3) overlap three times at the position of pixel A_i. Pixel C is only being overlapped by two patches (B1, B2).

Programmatically, how do I count how many times a pixel has been overlapped AND know its index? I am going to do this in the whole image.

Thanks!

Actually, the patch is 3D and so is the image. Så the patch contains 3x3x3 voxels. It will be moving around the image with and overlap on 1. Therefore not all voxels are going to be processed the same amount of times. I have tried add 1's on the position of the processed voxel. But I will get unique numbers from 0-18 of the whole image. Is that even possible?
