Abstract

A method of digital color-image processing is described that leads to the equalization of the brightness histogram and of conditional saturation histograms for each hue area. Means for solving problems that arise in the practical realization of the method are considered. Color equalization can be directly used for preparation of color images for interpretation and for the enhancement of color pictures for visual quality. In the first case, application of the method can result in an increase of the visibility of objects that are initially almost indistinguishable. In the second case it leads to multicolored pictures with unchanged color features.
