中文说明：在MATLAB中求图像纹理特征，数学方法是部分子空间法，在matlab环境中自动识别连通区域的大小,包含位置式PID算法、积分分离式PID，这个有中文注释，看得明白，MinkowskiMethod算法 。
English Description：
In MATLAB for image texture feature and mathematical method is part of the sub space method, in the MATLAB environment, automatic recognition of connected region size and contains position type PID algorithm, integral separation PID, the Chinese notes, to understand it, MinkowskiMethod algorithm is presented.
