You could start writing, since it isYOUR project, not ours to do. Of course, if you are willing to send us your instructors e-mail address sows can get the credit, and some compensation for our work, we might do something.

[Walter Roberson]

1. measure size of uncompressed image
2. do adaptive arithmetic coding on image, producing compressed image
3. calculate the ratio of the size of the uncompressed image divided by the size of the compressed image

The File Exchange is here. I don't gaurantee you'll find what you need there, but you won't find freely available code at any other Mathworks site.
