In this paper, a novel filter based on the non- local mean (NLM) filter is to improve the denoisingeffect. Bilateral filtering for MRimages. Its formulation and implementation are easy but the performance of bilateral filter depends upon its parameter. We have applied bilateral filtering on ...
Non-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 underlying structures/signals from noise. In PET (or SPECT) ...
A new image denoising algorithm to deal with the Poisson noise model isgiven, which is based on the idea of Non-Local Mean. By using the "Oracle"concept, we establish a theorem to show that the Non-Local Means Filter caneffectively deal with Poisson noise with some modification. Under the...
Background Image denoising is an important topic in the digital image processing field.This study theoretically investigates the validity of the classical nonlocal mean filter(NLM)for removing Gaussian noise from a novel statistical ...

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...
A new image denoising method combined a Pyramidal Dual-tree Complex Directional Filter Bank(PDTDFB)domain Gaussian Scale Mixture(GSM)model and a non-local mean filter was proposed.First,the locally coefficients PDTDFB(GSM)model for a noisy image was established,and the denoised coefficients were ...
Non-local means filter (NLMF)Peak signal-to-noise ratio (PSNR)Mean structural similarity (MSSIM)Image denoising is always the basic problem of image processing, and the main challenge is how to effectively remove the noise and preserve the detailed information. This paper presents a new image ...
首先根据non-local mean operation,作者定义了通用的non-local operation: y(i)=\frac{1}{\mathcal C(x)}\sum\limits_{\forall j} f(x_i, x_j)g(x_j) 很眼熟啊,很attention is all you need 里面我推导的公式几乎一摸一样,f计算两个量之间的关系,x代表输入,y代表输出,\mathcal{C(x)}代表归一...
