Abstract: Images having low contrast are usually captured in dark or bright environments. So preprocessing of such images becomes necessary to make the images suitable for other image processing applications. Image enhancement is a common problem. The histogram equalization (HE) technique is widely used for this purpose because it is simple and effective. However, it produces undesirable visual artifacts in the output image because the mean brightness of the image is changed. This paper presents a review of different techniques that can be used for contrast enhancement. The ultimate aim of these techniques is to preserve the input mean brightness so that the image looks natural in appearance.
