ABSTRACT:
A device for segmenting textured images on the basis of digital signals which are representative of said images by characterization of each texture by using representative parameters and by decomposition of each image into regions associated with different textures, said device comprising, for said characterization of the texture, a sub-assembly (100) for directional morphological filtering and a sub-assembly (200) for determining the texture parameters, and, at the output of this sub-assembly (200), a sub-assembly (300) for segmentation into regions by means of the technique of extracting watershed lines in a texture parameter image subdivided into blocks of a given size. A sequencing stage (600) furnishes the different control signals of said sub-assemblies.
