摘要
We are interested in the restoration of blurred colour images corrupted by additive noise. We present a new model for colour image enhancement based on coupling diffusion to shock filter without creating colour artefacts. The suggested model is based on using single vectors of the gradient magnitude and the second derivatives in order to relate different colour components of the image. (C) 2017 Elsevier Ltd.
