I'm having a hard time finding a tutorial that explains how to do image stitching. I've read https://ramsrigoutham.com/2012/11/22/panorama-image-stitching-in-opencv/, but it's only a code example, and not an actual tutorial.
Are there any good tutorials in C++ that would explain how image stitching?
What I'm trying to do is stitch images that are created on a computer (eg. screenshots), which will be consistently the same orientation, resolution, angle, etc. The only thing that differs is the offset, which isn't consistent.
How do I go about stitching these images so that they are matched pixel-perfect?
