A collection of C programs that do string matching and pattern discovery. This appears to be free code by D. Gusfield, who also has a book called “Algorithms on Strings, Trees and Sequences: Computer Science and Computational Biology”.
One DCL reader commented The strmat package is wonderful.

Tiling and Adapative Image Compression
This paper appears to discuss the concept of compressing images by breaking them down into small pieces and doing some sort of optimal compression on each piece. I assume the trick here is to locate the point of diminishing returns.
