Hello to everyone, I wanted to ask you advice. My goal is to create an algorithm that succeeds with a good percentage, to see if two pictures are similar. I have a master photo and all the photos i want to compare with this to see if they are "the same". I wanted to divide the algorithm in 3 points.
1)Load photo to compare and adjust brightness, contrast, histogram 2)I adjust the perspective by calculating matrix h with the original photo 3)I make the difference between the master picture and this (absdiff)
My problem is: how do I get a similar picture to that master in brightness and contrast
