This paper presents an efficient technique for performing a spatially inhomogeneous edge-
preserving image smoothing, called fast global smoother. Focusing on sparse Laplacian …

In this article, the author presents a practical and accessible framework to understand some
of the basic underpinnings of these methods, with the intention of leading the reader to a …

One of the most challenging issues in color guided depth map restoration is the
inconsistency between color edges in guidance color images and depth discontinuities on …

Non-local methods for image denoising and inpainting have gained considerable attention
in recent years. This is in part due to their superior performance in textured images, a known …

We introduce a fast convolution-based method (FCBM) for solving linear and a certain class
of nonlinear peridynamic (PD) transient diffusion problems in 1D, 2D, and 3D. The method …

Many natural or texture images contain structures that appear several times in the image.
One of the denoising filters that successfully take advantage of such repetitive regions is NL …

With the development of communication technology and network technology, as well as the
rising popularity of digital electronic products, an image has become an important carrier of …

We introduce a unifying energy minimization framework for nonlocal regularization of
inverse problems. In contrast to the weighted sum of square differences between image …

This paper presents an extension of the Non-Local Means denoising method, that effectively
exploits the affine invariant self-similarities present in the images of real scenes. Our method …

Purpose To develop an image noise filter suitable for MRI in real time (acquisition and
display), which preserves small isolated details and efficiently removes background noise …
