You can use the Image Processing Toolbox. Do you have that? Here are instructions:

1. Check to see if you have the IP Toolbox. If not, buy it.
2. Write your own custom algorithm to do the comparison on sample pictures.
3. Test against a bunch of other pictures to see how robust it is. Tweak if necessary.
4. Roll out your app to other users for use on their images.

Good luck.
