A method for characterizing an object in a digitized image includes providing (41) a digitized volumetric image comprising a plurality of intensities corresponding to a domain of points in an N-dimensional space, forming (42) a toboggan cluster from a subset of contiguous points in said image, said toboggan cluster including a concentration point, extracting (44) a first layer from said toboggan cluster, and computing (45) one or more features from said toboggan layer
L~invention décrit un procédé pour caractériser un objet dans une image numérisée qui inclut la fourniture (41) d~une image volumétrique numérisée comprenant une pluralité d~intensités correspondant à un domaine de points dans un espace de dimension N, la formation (42) d~un groupe de toboggan à partir d~un sous-ensemble de points contigus dans ladite image, ledit groupe de toboggan incluant un point de concentration, l~extraction (44) d~une première couche dudit groupe de toboggan, et le calcul (45) d~une ou plusieurs caractéristiques de ladite couche de toboggan.
