Tang2003 enhance the contrast of the image measure algorithm in compressed domain thesis papers URL: http://ieeexplore.IEEE.org/stamp/stamp.jsp?TP=&arnumber=1232722 consider algorithms of the main content of this paper: An image enhancement algorithm for images compressed using the JPEG standard is presented. The algorithm is based on a contrast measure defined within the discrete cosine transform (DCT) domain. The advantages of the psychophysically motivated algorithm are 1) the algorithm does not affect the compressibility of the originalimage because it enhances the images in the decompression stage and 2) the approach is characterized by low computational complexity. The proposed algorithm is applicable to any DCT-based image compression standard, such as JPEG, MPEG 2, and H. 261.
