Title (EN) METHOD FOR PROCESSING A HDR IMAGE TO COMPENSATE VEILING GLARE INTRA-OCULAR EFFECT
(FR) PROCÉDÉ DE TRAITEMENT D'UNE IMAGE HDR PERMETTANT LA COMPENSATION D'UN EFFET INTRA-OCULAIRE D'ÉBLOUISSEMENT PAR RÉFLEXION
Abstract:
(EN) Method comprising : - detecting in input image pixels that induce glare, then, - for each pixel q, computing a level of glare LG, q that is induced by detected pixels and that overlaps said pixel q, computing an increase of contrast to apply to pixel q based on said computed level of glare LG, q, and applying said computed increase of contrast to said input image.
(FR) L'invention concerne un procédé comprenant : la détection dans une image d'entrée de pixels qui induisent un éblouissement, puis : pour chaque pixel q, le calcul d'un niveau d'éblouissement LG, q induit par des pixels détectés et qui chevauche ledit pixel q, le calcul d'une augmentation du contraste à appliquer au pixel q en fonction dudit niveau d'éblouissement LG, q, calculé et l'application de ladite augmentation du contraste calculée à ladite image d'entrée.
