Abstract

Contrast enhancement is one of the fundamental techniques in the processing chain for improving the quality of an image, which is under- or overexposed. The existing enhancement methods are often used in an interactive manner which supposes a subjective choice of these methods and of the parameters on which they depend. We have therefore developed a method which allows the automatic enhancement of images by introducing decisional criteria for the choice of the adapted transfer function. The decisional criteria are based on the dynamics and the first two statistical moments of the histogram of the image to be processed.
