Title (EN) SYSTEMS AND METHODS FOR NORMALIZING AN IMAGE
(FR) SYSTÈMES ET PROCÉDÉS DESTINÉS À LA NORMALISATION D'UNE IMAGE
Abstract:
(EN) A method for normalizing an image by an electronic device is described. The method includes obtaining an image including a target object. The method also includes determining a set of windows of the image. The method further includes, for each window of the set of windows of the image, predicting parameters of an illumination normalization model adapted to the window using a first convolutional neural network (CNN), and applying the illumination normalization model to the window to produce a normalized window.
(FR) La présente invention concerne un procédé destiné à la normalisation d'une image au moyen d'un dispositif électronique. Le procédé consiste à obtenir une image comprenant un objet cible. Le procédé consiste également à déterminer un ensemble de fenêtres de l'image. Le procédé consiste en outre, pour chaque fenêtre de l'ensemble des fenêtres de l'image, à prédire les paramètres du modèle de normalisation d'éclairage adaptés à la fenêtre au moyen d'un premier réseau neuronal convolutif (CNN), et à appliquer le modèle de normalisation d'éclairage à la fenêtre de manière à produire une fenêtre normalisée.
