Abstract (en)

[origin: WO2015033058A1] The present invention relates to an image processing method including the following steps: receiving (100) a deformation or displacement image; defining a meshing (300) of the deformation image; assigning a respective pair of unknown variables to each node of the meshing; detecting one (or more) node(s) located at the boundary between two different materials of the body studied; enriching (400) the node(s) detected; calculating a basic matrix (500) for each basic cell of the meshing; assembling (600) the basic matrixes in order to obtain an overall structural matrix; calculating (700) a resilience image of the body based on the overall structural matrix.
