Abstract

Various methods are used to remove the noise from the digital images, such as Median filtering, mean filtering, Gaussian filtering anisotropic filtering, Vectorial total Variation (VTV), etc. Many of the algorithms removes the fine detail and structure of the noise along with the noise because assumption are made about frequency content of an image. In this paper, non-local means algorithm is proposed to overcome the drawback of existing methods. Non-Local means algorithm take the value of group of pixels surrounding the target pixel to smooth an image. The performance of non-local means algorithm compared with the existing method.
