Digital images are noisy due to ecological disturbances and it is degrade the quality of images. Data sets collected by image sensors are generally infected by noise and it is due to imperfect instruments. The noise is characterized by its pattern and by its probabilistic characteristics. There is a wide variety of noise types while we focus on the most important types of noises and comparative analysis of denoising techniques for corrupted images to enhance image quality is discussed in this paper. There have been several published algorithms and each approach has its assumptions, advantages and limitations. This paper presents a review of some significant work in the area of image denoising in terms of PSNR and ENL with different noise level.
