A method for determining the areas and volumes of structures from an image. A digital image is acquired (410), enhanced (418), and parallel processed by intensity-based segmentation (422) and edge-based segmentation (438) methods. After segmentation by both processes, the images are combined by an AND Operator (442), and polished (464). The segmented image is then outputted (480) and the Area or Volume of the structure is computed (484).

L'invention porte sur un procédé permettant de déterminer les surfaces et volumes de structures à partir d'images, selon lequel on acquiert (410) une image qu'on agrandit (418), puis traite en parallèle par segmentation (422) sur la base d'intensités et par segmentation (438) sur la base de bordures. Lesdites segmentations effectuées, on combine les images à l'aide d'un opérateur ET (442), puis on les polie (464). Les images segmentées ayant été extraites (480), on calcule (484) la surface ou le volume de la structure.
