  • Abstract
    In this paper, a new model for color image enhancement based on diffusion-shock filter coupling is presented. The proposed method is based on the consideration of single vectors of the gradient magnitude and the second derivatives as a manner to relate the processing of the different color components of the image. This solution avoids the apparition of color artefacts in the enhanced image.
