中文说明：这个程序中使用的灰度级共生矩阵（GLCM）来计算纹理属性。该GLCM是组合体素的幅度/亮度值（灰度级）的频率不同发生在分析窗口列表。
English Description：
This program use the gray-level co-occurrence matrix (GLCM)to compute the texture attribute. The GLCM is a tabulation of how often different combination voxel amplitude/brightness values(gray levels) occur in an analysis window.
