Abstract :
The state-of-the-art exact histogram specification algorithm by Coltuc and others is improved. We use the image generated by this method as our initial starting point and improve its visual quality by application of several histogram-invariant transformations on the image, making it more and more similar to the source image. Experimental results verify the superb performance of the proposed method.
