Geoff Boynton has a nice webpage for a Special Topics in Vision class he gave a few years ago. The class website includes a linked list of influential papers on vision, with an emphasis on papers with a strong computational component. Also available is a zip file with a large number of matlab functions demonstrating different computational models/vision concepts, including:

• The Rust model of MT – including model fitting and demonstration movies
• Contrast normalization
• Spike-triggered averaging
• Linear, LN, and quadrature pair models of V1 cells
• and much more
