> Just like a blind programmer could code a program to tell if an image is red or blue
Uh I'm sorry but I think it's not as easy as it seems. A pixel? Sure it's easy just compare whether the blue is bigger than red value. For image, I don't think it's as easy.
This is outside the bounds of the point OP was making, but FWIW an image is ultimately just a grid made up of pixels. You need only to loop your pixel classifier over the 2d array and tabulate.
