Medical image denoising: A brief analysis

An image is nothing but a pictorial representation of an object. Image without any disturbance or noise is generally best suitable for use. But if the image is corrupted with noise then that is of no value. So denoise is a kind of concept which is taken into consideration to remove noise. In this paper, I have reviewed some of the papers in the field of denoising particularly in the field of medical technologies. There are abundant number of papers released in this area. Some are having some advantages and some disadvantages. Ultimate approach of image denoising is that, we need to denoise the image in such a way so that features of images like edges, corners and other valuable features would not be removed. The ultimate aim of researchers is to get the true image from the denoised image with the probability of success as 1.Hence,this paper is not only meant for reviewing the papers based on denosing techniques but also provides a future direction to extend for further research in this area of medical image denosing.
