Abstract

A method and apparatus use a variational approach for gamut mapping. An algorithm that is applied to the color values minimizes a variational problem or penalty function. In this function the difference between the initial and the final image and the difference of gradients between these images are accounted for. In one embodiment an image pyramid having fine to coarse resolution layers is constructed and the process starts by using the coarest resolution layer. A quadric programming efficient numerical solution provides real-time results.
