一、引言纹理分析(Texture Analysis)是数字图象处理和模式识别研究中的一个重要方面。无论从理论或常识出发,纹理结构都显然应该成为描述与识别图象的一项重要依据。与其他图象特征或描述相比,纹理性质似乎能够更好地兼顾图象宏观性质与细部结构两个方面。纹理概念就其直观意义而言应该是清楚的。但在图象处理中的“纹理”一词却有着广泛笼统的含意,以致至今还没有确切的定义。 I. Introduction Texture Analysis is an important aspect of digital image processing and pattern recognition research. Whether from theory or common sense, the texture structure should obviously become an important basis for describing and identifying images. Compared with other image features or description, the texture property seems to be able to take better account of both the macroscopic and detailed structure of the image. The concept of texture should be clear in its intuitive sense. However, the word “texture” in image processing has a wide range of general meaning, so far there is no exact definition.
