A REVIEW PAPER: NOISE MODELS IN DIGITAL IMAGE PROCESSING

WebQuestion: Topic: Matlab Image Processing Given a noisy image and its original image, analyze and identify the types of noise in the image (eg.Gaussian, Rayleigh, Erlanga, Uniform, etc) and generate the noise to match the given image. I have found out through histogram that noisy1.jpg contains Gaussian noise but am having trouble detecting the … Webnoise can be of various types like Gaussian noise, Salt and Pepper noise, Rayleigh noise etc. which hampers the quality of the image. The quality can be improved by using various filters depending on the requirement. In this paper we have discussed the two types of filters for smoothening Butter slow movement exercise routine
