Improved Non-local Means Filtering Algorithm [PDF]
Jisuanji gongcheng, 2016 The non-local means filtering algorithm is an efficient denoising algorithm that can restore details of image texture well.However,the algorithm cannot adaptive adjust filtering parameters and the filtering result is easy to produce artifacts.Owing to ...

Entropy-Based Non-Local Means Filter for Single-Look SAR Speckle Reduction
Remote Sensing, 2022 Speckle is an interference phenomenon that contaminates images captured by coherent illumination systems. Due to its multiplicative and non-Gaussian nature, it is challenging to eliminate.

Non-Local Means Hole Repair Algorithm Based on Adaptive Block
Applied Sciences, 2023 RGB-D cameras provide depth and color information and are widely used in 3D reconstruction and computer vision. In the majority of existing RGB-D cameras, a considerable portion of depth values is often lost due to severe occlusion or limited camera ...

Non-Local Means De-Speckling Based on Multi-Directional Local Plane Inclination Angle
Remote Sensing, 2023 The unavoidable speckle in SAR images seriously interferes with image quality and has a negative effect on subsequent image interpretation. The existing filters still need to be strengthened in terms of both noise suppression and edge preservation. Based

Noise Reduction in ECG Signal Using an Effective Hybrid Scheme
IEEE Access, 2020 Electrocardiogram (ECG) is a critical biological signal, which usually carries a great deal of essential information about patients. The high quality ECG signals are always required for a proper diagnosis of cardiac disorders.

Image Processing On Line, 2011 We present in this paper a new denoising method called non-local means. The method is based on a simple principle: replacing the color of a pixel with an average of the colors of similar pixels. But the most similar pixels to a given pixel have no reason
