Abstract

Image De-noising has remained a fundamental problem in the field of image processing. To reducing noise from the original signal is still a challenging for researchers. There are several algorithms and methods each having assumptions, advantages ,and disadvantages. Noise can be introduced by transmission errors and compression This paper presents a review of some significant work in the area of image de-noising. After a brief introduction, some popular approaches are classified. An overview of various algorithms and methods is provided. In this paper Thus, de-noising is often a necessary and the step to be taken before the images data is analyzed. It is necessary to apply an beneficial de-noising technique to compensate for such data corruption future trends in the area of de-noising are also discussed
