 Course Outline, Readings, and Software

This course explores some of the most successful ideas in computer vision at an introductory level. Linear algebra and probability are prerequisites, but the class will be essentially self-contained. For each of the following topics, we will cover the basic concepts, look at one or two algorithms that work well, and discuss limitations and possible extensions. The numbers of lectures indicated for each topic are approximate.
