An Algorithmic Analysis of Variational Models for Perceptual Local Contrast Enhancement

Abstract

Color cast cancellation and local contrast enhancement are very important problems in computervision. In this paper we review the algorithm proposed by Palma-Amestoy et al. [A perceptuallyinspired variational framework for color enhancement, IEEE Transactions on Pattern Analysisand Machine Intelligence, 21 (2009), pp. 458–474], present results and evaluate the impact of achange in the parameters.
