Summary: | The invention relates to a method for characterizing a fibrous structure from a volumetric image, said fibrous structure having a three-dimensional weave between a plurality of warp threads extending in a first direction and a plurality of weft threads extending in a second direction perpendicular to the first direction, the method comprises: performing a first processing (E10) of the volumetric image by filtering in a third direction perpendicular to the first and second directions to attenuate a periodic pattern in the third direction; obtaining (E20) a two-dimensional image corresponding to a median plane along a third direction of the filtered volumetric image; performing a second process (E31, E41) on the two-dimensional image by filtering in the first direction or a second direction to attenuate the periodic pattern; obtaining (E32, E33) a one-dimensional profile representing the position of the warp or weft column and corresponding to an intermediate line along said first or second direction of the fil |
