Hello all, I was wondering if anyone could help me figure out a way to compare two pieces of two images that have overlap. I want to check for similarities in parts of the image, so that I can position them properly to each other. I thought about just checking the farthest right rows of pixels against the farthest left rows of the second image, but i'm not sure where to begin with it all as far as coding goes. Is there a way to store that specific pixel info, and if I did store it, how would I compare them? Thanks!
