灰度共生矩阵反映了图像灰度关于方向、相邻间隔、变化幅度的综合信息，它可作为分析图像基元和排列结构的信息。作为纹理分析的特征量，往往不是直接应用计算的灰度共生矩阵，而是在灰度共生矩阵的基础上再提取纹理特征量。该段代码是对纹理特征的提取。-Gray symbiotic matrix reflects the image grey about the direction, and adjacent interval, change the amplitude of the comprehensive information, it can be used as the base and arrangement structure image analysis of information. As texture analysis of characteristic features, more often than not, direct application of gray symbiotic matrix calculation, but in the gray symbiotic matrix based on texture feature extraction is again. When the code is to the extraction of the texture characteristics.
