Abstract

: Image noise removal has become an important research direction in the field of computer science because of the vast development and peaking demand of its applications.. Noise, the most common degrading factor, affects the visibility of the images and makes them unclear. Noise which is also called as an unwanted electrical or electromagnetic energy that degrades the quality of signals and data. Attenuation deteriorates the scene contrast and air light increases the whiteness in the scene. Therefore, the removal of attenuation and airlight helps to restore the color and contrast of the images, making them haze-free. Different works have been proposed till date inorder to filter out noise from images. This paper analyses the different image noise removal techniques. The different techniques, along with their merits and demerits are discussed.
