Abstract— Principle objective of Image enhancement is to process an image so that result is more suitable than original image for specific application. Digital image enhancement techniques provide a multitude of choices for improving the visual quality of images. In this paper, I present an overview of image enhancement processing techniques in spatial domain. More specifically, we categorize processing methods based representative techniques of Image enhancement. Thus the contribution of this paper is to classify and review image enhancement processing techniques, attempt an evaluation of shortcomings and general needs in this field of active research and in last we will point out promising directions on research for image enhancement for future research.

Index Terms— Frequency domain techniques, Image enhancement, Spatial domain techniques, Histogram equalization
