Takes two pictures and subtracts them one from the other digitally. Then creates a new picture that represents the difference and also a plot that can be used for measuring features of the difference. Example pictures of wind tunnel shock angle measurements are included. Another example is included which shows how to find where the text message is hidden in a steganographically encrypted image. Images are include for both examples.
See the readme file which will walk you through the examples.
