Abstract :
Although the human eye can discern thousands of color shades and intensities compared to about two dozen shades of gray, there is a need for the enhancement of color images. In this paper an extension of the adaptive contrast enhancement method of Dash and Chatterji (1991) for colour images using RGB components is described. The algorithm is given and results are presented
