Contrast Enhancement with Chromaticity Error Bound
Abstract
All existing contrast enhancement methods focus on heightening of spatial details in the luminance channel, with no or little consideration of the color fidelity of the processed images; they can introduce highly noticeable distortions in hue and saturation. This long-time much overlooked problem is addressed by this paper. A new algorithm based on Wu's optimal contrast-tone mapping (OCTM) is proposed to make maximal gain of contrast while …
