中文说明： 数学方法是部分子空间法，包括AHP，因子分析，回归分析，聚类分析，实现了图像的灰度化并进一步用于视频监视控，可直接计算得到多重分形谱,未来线路预测,分析误差,包含了阵列信号处理的常见算法。
English Description：
The mathematical method is the partial subspace method, including AHP, factor analysis, regression analysis and cluster analysis, which realizes the graying of the image and is further used in video monitoring and control. It can directly calculate the multifractal spectrum, predict the future line, analyze the error, and include the common algorithms of array signal processing.
