Multi-scale Total Variation with Automated Regularization Parameter Selection for Color Image Restoration

In this talk, we are concerned with the multi-scale total variation model for image restoration. Since the parameter controls the trade-off between the image smoothness and the preservation of details, we consider a spatially dependent choice and propose an iterative method to determine a set of (local) parameters corresponding to the image regions pertinent to different scales. Based on a prim...

Spatially dependent regularization parameter selection in total generalized variation models for image restoration

The automated spatially dependent regularization parameter selection framework of [9] for multi-scale image restoration is applied to total generalized variation (TGV) of order two. Well-posedness of the underlying continuous models is discussed and an algorithm for the numerical solution is developed. Experiments confirm that due to the spatially adapted regularization parameter the method all...

Scale Recognition, Regularization Parameter Selection, and Meyer's G Norm in Total Variation Regularization

We investigate how TV regularization naturally recognizes scale of individual image features and we show how perception of scale depends on the amount of regularization applied to the image We give an automatic method for nding the minimum value of the regularization parameter needed to remove all features below a user chosen threshold We explain the relation of Meyer s G norm to the perception...

An Iterative Regularization Method for Total Variation-Based Image Restoration

We introduce a new iterative regularization procedure for inverse problems based on the use of Bregman distances, with particular focus on problems arising in image processing. We are motivated by the problem of restoring noisy and blurry images via variational methods, by using total variation regularization. We obtain rigorous convergence results, and effective stopping criteria for the gener...

Iterative Nonlocal Total Variation Regularization Method for Image Restoration

In this paper, a Bregman iteration based total variation image restoration algorithm is proposed. Based on the Bregman iteration, the algorithm splits the original total variation problem into sub-problems that are easy to solve. Moreover, non-local regularization is introduced into the proposed algorithm, and a method to choose the non-local filter parameter locally and adaptively is proposed....
