IMPORTANT INSTRUCTIONS: For each lecture, students are required to read the assigned paper before the lecture and submit a one-page document related to the assigned paper. It should contain two parts: a summary of your understanding of the paper, and your observations about the paper. Observations can include difficult points in the paper, interesting ideas or future extensions. This summary is due at the beginning of the lecture.

Chris Stauffer, W.E.L. Grimson
Adaptive Background Mixture Models for Real-Time Tracking
Proceedings of IEEE Conf. on Computer Vision and Pattern Recognition (CVPR), Fort Collins, CO, pp. 246-252, June 1999 [PDF]
Have a look at VSAM project page at MIT AI Lab. There are several interesting background subtraction examples on this page, in the form of java applets. Another associated publication is available here. Subtraction using gradient information was mentioned in class. That paper is available here. The Eigen-Background approach mentioned in class does not assume pixel-wise independence, and is described in this paper. Finally, if you are interested, another background subtraction method is available here. This still assumes pixel-wise independence, but uses a different strategy to medel the background. Also contains an interesting discussion on problems/issues in background subtraction.
