A signature is generated for a given picture by operating on it with different masks. The operations are gray level generalizations of “shrink” and “expand” for binary pictures using Serra's morphological methods . The signature is a set of numbers, each corresponding to an application of an operator at a certain scale and direction, and can be used to analyze the discriminate textures. It is shown that this family of signatures includes as special cases several currently used texture descriptors.
