Bits and Bytes : Math of Image Restoration

I've been looking for a simple introduction to image processing that would appeal to students with modest math backgrounds. Most image processing materials are written for electrical engineers and are way above the level of a typical non-math major.

So I was really glad to see this paper from the Electronic Proceedings of the Eighteenth Annual International Conference on Technology in Collegiate Mathematics, Orlando, Florida, March 16-19, 2006.

I'm planning to use it in my math for liberal arts course next time I teach it.
