摘要：Image Enhancement is one of the most essential and laborious techniques in image researches. The scheme of image enhancement is to improve the visual semblance of an image, or to afford a “correct transform representation for future automated image processing. Many images like medical images, satellite images, aerial images and even real life photographs suffer from indigent contrast and noise. It is necessary to enhance the contrast and remove the noise to enhance image quality. One of the most significant stages in medical images detection and analysis is Image Enhancement techniques which improves the quality (clearness) of images for human look, removing blurring and noise, increasing contrast, and unveil details are examples of enhancement operations. The enhancement technique varies from one field to another according to its objective. The existent techniques of image enhancement can be classified into two categories: Spatial Domain and Frequency domain enhancement. In this research, we present an overview of image enhancement projection techniques in spatial domain. More specifically, we categorise processing methods based typical techniques of Image enhancement. Thus the contribution of this paper is to arrange and review image enhancement procedure techniques, attempt an evaluation of shortcomings and universal needs in this field of active research and in last we will stage out promising directions on research for image enhancement for prospective research.
