How to know if an images is similar to another (slightly different angle but same point of view)

Question

I\'ve checked methods like Phasher to get similar images. Basically to resize images to 8x8, grayscale, get average pixel and create a binary hash of each pixel comparing if it\

Answer 1

You can try an upper bound if the hashes doesn't match compare how many pixels match from the 8x8 grid. Maybe you can try to match the colors like in photo mosaic:Photo Mosaic Algorithm. How to create a mosaic photo given the basic image and a list of tiles?.
