全变差图像恢复的自适应步长梯度投影算法
Gradient Pro jection Algorithm for Total Variation Image Restoration by Adaptive Steplength Selection Rules
摘要
Abstract
We propose a new gradient projection algorithm for image denoising based on the dual of total variation. The new method exploits nonmonotone line-search and adaptive steplength selection based on strategies for alternation of the well-known Barzilai-Borwein rules. The proposed method is much faster than the Chambolle0s gradient projection algorithm. Numerical results illustrate the efficiency of this method.关键词
