The invention concerns a method for identifying the anisotropy of the texture of a digital image, comprising: a) acquisition of a digital image; b) transformation of the acquired image by means of a modification of the image that comprises a rotation and a change of scale; then, for each applied modification, calculation of a K-increment; c) for each different transformed image, calculation of a p-variation Wj,k of said transformed image from said calculated K-increments; d) estimation, by regression analysis, of characteristic terms depending only on the rotation that has been carried out, then, testing of the equality of said terms relative to each other, the texture of the image being identified as isotropic if such equality is found and otherwise being identified as anisotropic. |
