Improve proprietary PHP jpeg image motion detection function

Please make this (currently working) motion detection function faster (a lot - at least 10x) - want to use it to compare single images to check for changes between jpeg images.

Optional: Also, it would be great if this function could deal with light and white balance changes (sun coming out behind the clouds, turning on a light) to prevent false positives. Maybe set with a different option.

Optional: Be able to save the diffs between the images in a proprietary format and be able to patch the previous image with the diff later

I have only implemented this quick and dirty in a few hours years ago - not saying it's the best or easiest or fastest way. Happy to be surprised. May require a PHP extension written in C / C++ - or some external image library.

The function should be able to deal with some random noise from a camera.

img_old = php image object (reference)

img_new_data = jpeg data / image as string

tlx=top left, bottom right etc. for the mask. rectangle - the mask will allow the function to ignore specific parts of the image to be excluded 0<=x<16, 0=<y<12

returns a value between 0 and 1000 - 0 = no change, 1000 = full black/white change - adjusted for the mask
