A STUDY ON IMAGE NOISE AND VARIOUS IMAGE DENOISING TECHNIQUES

Abstract

Nowadays processing of the image is an emerging science. The image is contributed in several research fields such as biomedical, security, education, and space. The phenomenon of corruption in the images due to the noise is a big obstacle. The main two reasons for appearing the noise are transmission process from place to place or it may happen during the acquisition process. On the other hand, there are a lot of techniques for removing the noise and retrieving the image quality by manipulating the image data. In this article, a brief study on the major noise types is introduced. Also, the study consists of the famous de-noising techniques especially, the two essential methods spatial domain and transform domain with its subparts.
