分形和空间灰度共生矩阵联合评价断口形貌研究

为了全面描述断口形貌特征，采用分形和空间灰度共生矩阵结合的方法，对4个典型断口形貌进行定量分析．结果表明：分形维数与断口的粗糙度和复杂度相关；灰度共生矩阵的每一个二阶统计参数都可以精确地描述断口形貌的某一特征，具有较好的纹理表达能力；将灰度共生矩阵的二阶统计参数和分形维数相结合组成多维特征集可以较完整地描述断口图像的纹理特征．分形和空间灰度共生矩阵的联合评价方法，可望实现断口类型的自动分类识别，同时对处理其它纹理图像具有一定的借鉴作用．

Research on Morphology of Fracture with Combined Method of Fractal and Spatial Gray Level Co-Occurrence Matrix

In order to describe the morphology of fracture objectively and quantitatively, four typical fractures were analyzed with the combined method of fractal and spatial gray level co-occurrence matrix. The study results show that the fractal dimension has relation with roughness and complexity of fracture, each of the 2-order statistical feature parameters of spatial gray level co-occurrence matrix can describe exactly a certain fracture texture character and have good texture expression abilities. By combined the fractal dimension with the 2-order statistical parameters of spatial gray level co-occurrence matrix as a set of feature parameters, the complexity and roughness of the fracture texture can be described effectively. This method may realize the quantitative analysis and automatic class identification for fracture texture, and can be used as a reference for other texture picture analysis.
