Hi, I'm writing a program that find differences between images. For now, I'm finding features with AKAZE, so I've the common point of the 2 images. The problem is that these 2 images have only a part in common. How can I extract the common part from both images? For better explanation: I need to extract the common part from the first image and then from the second, so I can do absdiff for finding difference.

Thanks to all!

I've resolved by using homography to map the common part from one image to another so I can crop it out!
