二维kalman滤波：基于Matlab，用Kalman滤波实现线性变化的电压测量滤波处理。其中主要参数为：电压测量方差 u = 0.1V；初始电压ub=10V；电压变化率du/dt = -0.02V/s。(Two-dimensional kalman filtering)

说明：  用subplot，imshow，imread，遍历并显示图库文件夹中的人脸图像（用循环）。运行后图像要显示成矩阵模式的，还得产生统一矩阵和均值矩阵。(With a subplot, imshow, imread, traverse and display the Gallery folder of face images (with circulation). After running into the matrix mode to display images, and have to produce unity matrix and the mean matrix.)

说明：  用于深度置信初步描述，适合初学者进行学习(Preliminary description of applicable depth confidence, initial learning)
