Image enhancement is a technique to bring out the detailed which is hidden in an image that is to increase the contrast of that part of the image where the information of the image lies. An image can be enhanced by using different enhancement techniques. Even though the image enhancement technique enhance the contrast of an image in an effective and efficient way, they usually have some drawbacks like loss in information, noise amplification and over enhancement. In this paper, an algorithm is proposed for image contrast enhancement using CLAHE, Intrinsic Decomposition and Dual Gamma Correction. As image decomposition is a highly critical problem, on both reflectance and illumination layers we have implemented some conditions .To avoid this problem intrinsic decomposition is used. Dual gamma correction is used to enhance the pixel intensities. There are four quantitative measuring parameters such as total variation (TV), average mean brightness error (AMBE) , enhancement measure error (EME), CQE is used to measure the quality of the enhanced image.
