Multi-scale total variation with automated regularization parameter selection for color image restoration

Abstract

In this paper, a multi-scale vectorial total variation model for color image restoration is introduced. The model utilizes a spatially dependent regularization parameter in order to preserve the details during noise removal. The automated adjustment strategy of the regularization parameter is based on local variance estimators combined with a confidence interval technique. Numerical results on images are presented to demonstrate the efficiency of the method. © 2009 Springer Berlin Heidelberg.
