The present disclosure relates to an image processing method including the following steps: receiving a deformation or displacement image； defining a meshing 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 the node(s) detected； calculating a basic matrix for each basic cell of the meshing； assembling the basic matrixes in order to obtain an overall structural matrix； calculating a resilience image of the body based on the overall structural matrix.
