It is as simple as you choose to perceive it. The problem you describe can
become very complex.

Apart from the naive absolute difference per pixel, you can use the shuffle
distance between images, Hausdorff distance or tangential distance.
To encode difference, look into wavelets or minimum description length
(MDL), based on Shannon's entropy.

It seems so.

It is a very fundamental problem that's broad in terms of applicability.
Tracking, modeling and face recognition are just a few that spring to mind.
