Summary:
Adverse illumination conditions can render face images very difficult to use in biometric authentication systems. In this paper, a methodology for contrast correction in images is presented. Proposed method, developed in the context of biometric applications, can as well be used in other domains where contrast correction of images is desired. The method is adaptable to quadtree-decomposed images and allows for definition of an arbitrary contrast correction function.
