Getting pixel value from Picture object is incredibly slow

I am trying to create my own custom image comparison algorithm. The first, what I thought, simple step would be to iterate over the each pixel in each image and compare them.  This however is so slow...

I guess I'm not understanding how this pixel by pixel comparison or otherwise alternative method is preferable over the existing Region.Compare method. 2000 x 2000 is literally going through 2 million pixels... twice (once for each picture) and the color data for each.... that's 4 million pixels being checked by pairs...

There are probably other utils available out there if the existing compare functions in TC don't suffice, but certainly I wouldn't do anything like this nested for loop deal...
