提取纹理特征参数,主要是灰度共生矩阵源代码，用于图像处理-gray level co-matrix source code,used for the image processing, to get the texture features

计算灰度共生矩阵，本程序可以计算任意偏移角度和距离的弧度共生矩阵，同时经过测试，比matlab自带graycomatrix计算结果更准确。-Calculation GLCM, this program can be calculated at any angle and radian offset distance co-occurrence matrix, while tested, than matlab graycomatrix comes more exact calculations.
