Abstract
The invention concerns a method of analyzing a set of data representing physical quantities, including the steps of:decomposition (E20) of the set of data on a plurality of resolution levels,first segmentation (E21) of at least one sub-part of a given resolution level, into at least two homogeneous regions, said given resolution level not being the highest resolution level in the decomposition,characterized in that it includes the steps of:extraction (E81) of contour data from the result of the segmentation of the previous steps,second segmentation (E25) of at least one sub-part of the resolution level higher than the given level into at least one homogeneous region, as a function of the contour data extracted.
