Recursive non-local means filter for video denoising

open access: yesEURASIP Journal on Image and Video Processing, 2017
In this paper, we propose a computationally efficient algorithm for video denoising that exploits temporal and spatial redundancy. The proposed method is based on non-local means (NLM).

Anisotropic Weighted KS-NLM Filter for Noise Reduction in MRI

open access: yesIEEE Access, 2020
The topic of denoising magnetic resonance (MR) images is considered in this paper. More in detail, an enhanced Non-Local Means (NLM) filter using the Kolmogorov-Smirnov (KS) distance is proposed. The KS-NLM approach estimates the similarity between image

The validity analysis of the non-local mean filter and a derived novel denoising method

open access: yesVirtual Reality & Intelligent Hardware, 2023
Image denoising is an important topic in the digital image processing field. This paper theoretically studies the validity of the classical non-local mean filter (NLM) for removing Gaussian noise from a novel statistic perspective.

Fast non-local means with size-adaptive search window

open access: yesThe Journal of Engineering, 2016
In this study, the authors present a fast non-local means (NLM) image denoising algorithm with size-adaptive search window. On the basis of the edge gradient and direction of the noisy image, the proposed fast scheme divides all the pixels into ...

Fractional Total Variation Algorithm Based on Improved Non-local Means [PDF]

open access: yesJisuanji gongcheng, 2019
The traditional total variation algorithm is mostly affected by the staircase effect in the variation process,so it causes texture loss and over-smoothing in the reconstructed image.Therefore,a reconstruction algorithm based on improved non-local means ...

MODIFIED NLM MODEL FOR DESPECKLING ULTRASOUND IMAGES USING FCM CLUSTERING BASED PRE CLASSIFICATION AND RIBM [PDF]

open access: yesICTACT Journal on Image and Video Processing, 2018
Speckle noise is an inherent characteristic of ultrasound which reduces the classification accuracy of computer aided diagnosis (CAD) systems. A modified non local means (NLM) filter for despeckling ultrasound images is proposed in this article.

Compact rotation invariant descriptor for non-local means [PDF]

open access: yes, 2010
Non-local means is a recently proposed denoising technique that better preserves image structures than other methods. However, the computational cost of non-local means is prohibitive, especially for large 3D images.
