Different environmental illumination has a great impact on face detection and recognition. Automatic detection and radiant correction of highlighted region on face image is helpful to identify human faces correctly in a color image. In this paper we present a novel approach based on dichromatic reflection model to detect and remove highlight in face region.(More)
