Remove noise from the image through non-local means filtering. Theimnlmfiltfunction estimates the degree of smoothing based on the standard deviation of noise in the image. [filteredImage,estDoS] = imnlmfilt(noisyImage); Display the noisy image (left) and the non-local means filtered image ...
In this paper a general optimizing procedure is proposed for the non-local means (NLM) filter. It involves finding the optimal degree of smoothing, the size of the search window and the size of the comparison window for a series of Computed Tomography (CT) images. All of them contain ...

Image qualityNon-local meansFilteringIterative reconstructionNon-local mean (NLM) filtering has been broadly used for denoising of natural and medical images. The NLM filter relies on the redundant information, in the form of repeated patterns/textures, in the target image to discriminate the ...
Low-dose CT (LDCT) technique can reduce the x-ray radiation exposure to patients at the cost of degraded images with severe noise and artifacts. Non-local means (NLM) filtering has shown its potential in improving LDCT image quality. However, currently most NLM-based approaches employ a ...

Non-local Means Filtering (NLMF) has been a popular issue in the image filtering field.The existing NLMFs based pre-selections are analyzed,and it is pointed out that they all have deficiencies in terms of feature extraction from image patches.An adaptiv
