Title
(EN) BRIGHT SPOT REMOVAL USING A NEURAL NETWORK
(FR) ÉLIMINATION D'UN POINT LUMINEUX À L'AIDE D'UN RÉSEAU NEURONAL
Abstract
(EN)
A method for image capture includes identifying a bright spot in an image. A neural network is used to recover details in bright spot area through a trained de-noising process. Post-processing of the image is conducted to match image parameters of recovered details in the bright spot area to another area of the image.
(FR)
L'invention concerne un procédé de capture d'image comprenant l'identification d'un point lumineux dans une image. Un réseau neuronal est utilisé pour récupérer des détails dans une zone de point lumineux par l'intermédiaire d'un processus de débruitage entraîné. Un post-traitement de l'image est effectué pour faire correspondre des paramètres d'image des détails récupérés dans la zone de point lumineux à une autre zone de l'image.
