Image reconstruction with locally adaptive sparsity and nonlocal robust regularization
Sparse representation based modeling has been successfully used in many image-related inverse problems such as deblurring, super-resolution and compressive sensing. The heart of sparse representations lies on how to find a space (spanned by a dictionary of atoms) where the local image patch exhibits high sparsity and how to determine the image local sparsity. To identify the locally varying spa...
متن کاملWeighted Nonlocal Total Variation in Image Processing
In this paper, a novel weighted nonlocal total variation (WNTV) method is proposed. Compared to the classical nonlocal total variation methods, our method modifies the energy functional to introduce a weight to balance between the labeled sets and unlabeled sets. With extensive numerical examples in semi-supervised clustering, image inpaiting and image colorization, we demonstrate that WNTV pro...
متن کاملInvariant representation in image processing
The paper discusses the role of invariance in image processing, specifically the desire to discriminate against unwanted variations in the scene while maintaining the power to tell the difference between object-intrinsic characteristics and scene-accidental conditions. It provides an analysis and references of what are directly observables in a general scene.
متن کاملNonlocal Patch-based Image Inpainting through Minimization of a Sparsity Promoting Nonconvex Functional
We propose a convex model for nonlocal image inpainting that fills in missing or damaged areas with different convex combinations of available image patches. The visual quality of inpainted solutions is much better when patches are copied instead of averaged, and we show how this can be achieved by adding a nonconvex sparsity promoting penalty. To promote sparsity of a variable that is constrai...
متن کاملImage Processing with Nonlocal Spectral Bases
This article studies regularization schemes that are defined using a lifting of the image pixels in a high dimensional space. For some specific classes of geometric images, this discrete set of points is sampled along a low dimensional smooth manifold. The construction of differential operators on this lifted space allows one to compute PDE flows and perform variational optimizations. All these...
