Image comparison algorithm
So basically i need to write a program that checks whether 2 images are the same or not. Consider the following 2 images:
http://i221.photobucket.com/albums/dd298/ramdeen32/starry_night.jpg
http://i221.photobucket.com/albums/dd298/ramdeen32/starry_night2.jpg
Well they are both the same images but how do i check to see if these images are the same. I am only limited to the media functions. All i can think of right now is the width height scaling and compare the RGB for each pixel but wouldnt the color be different?
Im completely lost on this one, any help is appreciated.
*Note this has to be in python and use the (media library)
