Survey on Image Denoising Methods

Abstract

Noise removal is the vital need of every image processing tasks like segmentation, classification, object detection, etc. The SaP (Salt-and-Pepper) noise is projected by the highest and lowest intensity values. Many denoising methods are designed in the literature study to effectively remove the salt and pepper noise. This paper assesses image denoising to explore the positive and negative issues of eight benchmark methods. This work helps to the research people of image denoising for selecting the better method by considering various parameters.
