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.
