Abstract: We use an optimum quantizer according to an energy criterion to divide the histogram of the image into subintervals whose sizes are inversely proportional to the number of pixels affected. By establishing a correspondence between this quantizer and the evenly distributed one, we obtain a new image where the most frequent grey levels are expanded whereas those grey levels with less number of pixels are compressed.
