    Look up image correlation. This is the standard mathematical technique to compare the likeness of two images.

    Matlab has the facility to compile your code into executable. You need the right tolbox for that, and have to include the supplied library in your distribution. It is all explained better in the user manual.

    Try reading through this page for an introduction http://en.wikipedia.org/wiki/Digital_image_correlation

    It mainly talks about application in detecting deformation, but it can be applied to most displacements or comparing the likeness between two images. There is a link at the bottom pointing to a Matlab example.
