    Abstract :

    Histogram Equalization (HE) is a simple and effective image enhancement technique. But, it tends to change the mean brightness of the image to the middle level of the permitted range, and hence is not a very suitable for consumer product. While preserving the original brightness is essential to avoid annoying artifacts. To preserve brightness and to enhance contrast of images, numerous methods are introduced, but many of them present unwanted artifacts such as intensity saturation, over-enhancement and noise amplification. In this paper we review the various methods for histogram equalization.
