Abstract:
The method of histogram equalization for grey-level image enhancement is extended to color images in the paper. A method of direct 3-D histogram equalization is proposed which results in a uniform histogram of the RGB values. Due to the correlation between the bands, the principle on which grey-level (1-D) histogram equalization is based is not valid in the case of color images (3-D). This problem is alleviated by employing a histogram specification method where a uniform histogram is specified.<>
