Abstract: Image denoising is a classical linear inverse problem with applications in remote sensing, medical imaging, astronomy and surveillance.

This article addresses the image denoising problem using a non-local noise estimation based on the spatial redundancy offered by natural images. A low.

The non-local means (NLM) is an effective and popular denoising method that adjusts each pixel value with a weighted average of all pixels in the entire image.

The commonly used non-local means filter is not optimal for noisy biological images containing small features of interest because image noise prevents accurate ...

We propose a method to denoise multiple-coil acquired MR images. Both the non central-χ distribution and the spatially varying nature of the noise is taken ...

In this section, the proposed NLM-SAP approach is compared to state-of-the-art denoising methods on a large dataset of standard images at different noise levels.

We propose a new method where information regarding the local image noise level is used to adjust the amount of denoising strength of the filter.

Jan 6, 2020 · The experimental results showed that the proposed method FANLM can better preserve the image details and remove noise, and the computational ...
