Abstract

Contrast in an image is enhanced by mapping an input intensity value to an output intensity value in accordance with a mapping function. A mean intensity value of the image is determined. Co-ordinates of the mapping function are calculated in accordance with the mean intensity value and a plurality of predefined parameters. The mapping function is applied to the input intensity value for determining the output intensity, wherein the mapping function is generated dynamically for each image.
