Hi guys, my first post here :) I've just started learning opencv , I wanted to make a program which can compare two images and tell by percentage how similar they are. I just know you can subtract images and tell if they are exactly the same or not. But what I'm looking for is a more relative way to tell by percentage their similarity.
I'll appreciate if anyone can help me with this.
