Augmented Lagrangian method for Rudin-Osher-Fatemi image model
邵培強先生國立中央大學數學系 上午 10:00–12:00 鴻經館 107 室Abstract:
In this talk we will introduce the augmented Lagrangian method (ALM) [1, 2] for solving the Rudin-Osher-Fatemi total variation model [3]. The relation between ALM and split Bregman iteration will also be discussed.
