Detailed Description
The Local Contrast filter performs a locally adaptive, spatially varying contrast enhancement.
The amount of enhancement varies as a function of the existing contrast in the local neighborhood, expressed as the ratio of the global mean to the local standard deviation. Areas with low inherent contrast are enhanced more than areas which already have high contrast
