A non-local mean filter can be applied to the given electrophysiological signal, the non-local mean filter including a spatial filter component and an intensity filter component. The method can also include controlling parameters to establish weighting of each of the spatial filter component and the...
PETImage 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 ...

Additionally, the mean χ2 values in the spinal cord show that Rician NLM filtering significantly reduced error estimates in both lateral and dorsal columns (Fig. 4b). Reduced χ2 values both in the brain and the spinal cord, imply that accuracy of tensor estimation is significantly improved ...

Definition: Non-local means is a classical filtering algorithms that computes a weighted mean of all pixels in an image.Non-local Neural NetworksThe authors define a generic non-local opeartionyi=1C(x)∑∀jf(Xi,Xj)g(Xj)yi=1C(x)∑∀jf(Xi,Xj)g(Xj) It supports inputs of variable ...
摘要原文 Speckle-noise filtering is an extensive and key process in coherent interferometric techniques to obtain important and accurate information from the recorded interferogram or fringe pattern. The speckle-noise inherent to these interferograms, recorded by digital image sensors in these optical techn...
Post-acquisition image processing through NLM filtering was performed to enhance image clarity and structural boundaries. NLM algorithm was chosen for its property of spatial detail preservation [21]. Although denoising only modestly improved ex vivo micro-CT scans, Fig. 6Aa and Ba, due to the sc...
A Gaussian Blur filter is an example of a uniform local mean filter. Non-local image denoising algorithms have gained popularity in the last decade because, relative to many local means algorithms, post-filtering clarity is improved while the real detail loss is reduced. In a “non-local ...
