METHOD FOR ESTIMATING MORPHOLOGICAL CHARACTERISTICS OF A GEOMETRIC FORM

摘要

The invention relates to a method for estimating morphological characteristics of a geometric shape (FG) represented by a graph (GR2), said graph (GR2) comprising at least two levels of resolution, a parent node (p) of the level of the coarsest resolution of said two levels being attached to a set of child nodes of the other level of resolution of said two levels, characterized in that it comprises the steps of: - pairings (a4) of child nodes of said set of nodes, a child node being paired with itself or with another child node of said set as a function of one or more target permutations, - calculation (a5) of one or more values of a cost function (Cμ), associated with said pairing, - and calculating (a6) a symmetry coefficient of said parent node (p), said calculation using at least one of said values calculated in the previous step.
