(FR) METHODE ET SYSTEME DE DETECTION ET DE SEGMENTATION AUTOMATIQUES DE TUMEURS ET D'OEDEMES ASSOCIES (TUMEFACTION) DANS DES IMAGES A RESONANCE MAGNETIQUE (IRM)
Abstract: front page image
(EN)A method and system for segmenting an object represented in one or more input images, each of the one or more input images comprising a plurality of pixels. The method comprising: aligning the one or more input images with one or more corresponding template images each comprising a plurality of pixels; extracting features of each of the one or more input images and one or more template images; and classifying each pixel, or a group of pixels, in the one or more input images based on the measured features of the one or more input images and the one or more corresponding template images in accordance with a classification model mapping image properties or features to a respective class so as to segment the object represented in the one or more input images according to the classification of each pixel or group of pixels.
(FR)L'invention concerne un procédé et un système servant à segmenter un objet représenté dans au moins une image d'entrée, chacune des images d'entrée comprenant une pluralité de pixels. Ledit procédé consiste à aligner l'image d'entrée avec au moins une image de modèle correspondante renfermant une pluralité de pixels, à extraire des caractéristiques de chacune des images d'entrée et de modèle, et à classifier chaque pixel ou groupe de pixels dans l'image d'entrée en fonction des caractéristiques mesurées de l'image d'entrée et de l'image de modèle correspondante selon un modèle de classification mappant des propriétés ou des caractéristiques d'images à une classe respective, de manière à segmenter l'objet représenté dans l'image entrée, à partir de la classification de chaque pixel ou groupe de pixels.
