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 [10]. 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.
通过使用不同的掩模对给定的图片进行操作，为其生成一个签名。这些操作是 Serra 的形态学方法[10]对二值图片的“收缩”和“扩展”的灰度概括。签名是一组数字，每个数字对应于在特定尺度和方向上应用运算符的情况，可用于分析有区别的纹理。结果表明，该签名族包括几个当前使用的纹理描述符作为特例。
