IEEE TRANSACTIONS ON IMAGE PROCESSING 1 Noise parameter

Many conventional image processing algorithms such as noise filtering, sharpening and deblurring, assume a noise model of Additive White Gaussian Noise (AWGN) with constant standard deviation throughout the image.

Noise filtering SlideShare

Image processing allows a much wider range of algorithms to be applied to the input data and can avoid problems such as the build-up of noise and signal distortion during processing of images. Wavelet transforms have become a very powerful tool for de-noising an image. One of the most popular methods is wiener filter. In this work four types of noise (Gaussian noise , Salt & Pepper noise

Gaussian noise SlideShare

Filtering is an important and much used discipline in image processing. The goal is either to remove unwanted components such as noise, or to en-hance certain features, or simply as an artistic modi cation. Some lters act isotropically (gaussian blur), others have a preference with respect to some direction. In this article, a class of simple recursive lters in 2 dimensions are analyzed and
