    Abstract

    Variational principles appear in a vast number of scientific disciplines. They often provide a ‘view from above’ which permits to better comprehend and analyse problems. In this paper we show how variational techniques can be used to modelise perceptual color correction of digital images. We will show that the basic human visual phenomenology defines a unique class of functionals whose minimization gives rise to color enhancement. This framework provides a unified home for noticeable models of perceptual color correction, as e.g. Retinex.
