DATE: 4/4/05 TIME: 1:10 pm in Weber 223 SPEAKER: Nigel Boston, University of Wisconsin, Department of Mathematics TITLE: Invariant-Based Face Recognition ABSTRACT: After a brief review of recent striking applications of algebra to engineering and computer science, the currently significant problem of face recognition is addressed. We introduce a new approach to obtaining invariants of Lie groups adapted to this problem and describe its success in implementations.
