Besov空间下迭代全变差正则化的图像恢复模型
Iterative total variation regularization for image restoration in Besov spaces
摘要
Abstract
An iterative regularization procedure in Besov spaces for image restoration is generalized. By using a suitable sequence of penalty parameters,the issue of solvability of minimization problems arising in each step of the iterative procedure is solved. The generalized iterative regularization procedure can be considered as a combination of soft-thresholding and hard-thresholding. Moreover, an effective stopping criteria and convergence result for the procedure are obtained. The numerical results indicate that the iteration procedure yields high-quality reconstructions and converges faster than the Xu-Osher method.关键词
