ABSTRACT
The main purpose of Image enhancement is to process an image to ensure that results are more desirable than the original image for a particular application. Digital image enhancement techniques offer a plethora of alternatives for improving the visual quality of the images. Suitable choice of such techniques is significantly influenced by the imaging modality, task and the viewing conditions. This paper gives an overview of fundamental concepts, as well as algorithms common for image enhancement. In this paper, instead of using normal images, the image enhancement methods are being used for medical images as the basic approach for reading, analyzing and applying some enhancements to medical images is much more complex as compared to normal images.
