Image enhancement (IE) is the process of enhancing visual appearance of image in order to make it more effective for computer to process. The look and visibility of image rely on human eyes, which vary from one person to another. Several enhancement methods are used to improve the clarity of image, but different application require different types of techniques for enhancing image quality. In this review paper, we present different enhancement techniques categorized into spatial and frequency domain to classify image quality with its advantage and disadvantage. This paper proposed an effective algorithm. TGC to enhance the medical image which gives better result the TGC comparatively. Experiment result provide accuracy of the range value.
