Image Denoising Methods. A New Nonlocal Principle
The search for efficient image denoising methods is still a valid challenge at the crossing of functional analysis and statistics. In spite of the sophistication of the recently proposed methods, most algorithms have not yet attained a desirable level of applicability. All show an outstanding performance when the image model corresponds to the algorithm assumptions but fail in general and creat...
متن کاملImage and movie denoising by nonlocal means
Neighborhood filters are image and movie filters which reduce the noise by averaging similar pixels. The object of the paper is to present a unified theory of these filters and reliable criteria to compare them to other classes of filters. First a CCD noise model will be presented justifying this class of algorithm. A classification of neighborhood filters is proposed, including classical image...
متن کاملInfrared image denoising by nonlocal means filtering
The recently introduced non-local means (NLM) image denoising technique broke the traditional paradigm according to which image pixels are processed by their surroundings. Non-local means technique was demonstrated to outperform state-of-the art denoising techniques when applied to images in the visible. This technique is even more powerful when applied to low contrast images, which makes it tr...
متن کاملRotationally invariant similarity measures for nonlocal image denoising
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 the nonlocal means filter. It is simple and yields very good denoising results. Unfortunately, the block matching within the standard nonlocal means filter is not able to handle rotation or mirroring. Rotated or mir...
متن کاملNonlocal Collaborative l0-Norm Prior for Image Denoising
Spatially adaptive nonparametric regression estimation is one of the most promising recent directions in image processing. The Transforms and Spectral Techniques Research Group at the Department of Signal Processing, Tampere University of Technology, has been active in this novel eld starting from about 2002. The results achieved with application to di¤erent image and video processing problems...
