                           Dual Methods for Total Variation-Based Image Restoration


                               February 25, Monday, Room 207, 1:00 pm.

Abstract.  This talk will describe a computational method for the inverse
problem of edge-preserving image restoration. Total Variation (TV)
regularization removes noise from an image while retaining its edges. We
solve an equivalent dual version of the TV problem. Images restored using
this dual approach will have crisp edges (discontinuities), whereas images
recovered under earlier primal methods may contain blurred edges. Joint work
with Tony Chan, Pep Mulet, and Lieven Vandenberghe.
