此程序为MATLAB环境下编写的用于对图像的平均梯度进行计算 从而对图像的清晰度 图像的质量进行评价的代码。(This program is written in MATLAB environment is used to calculate the average gradient image sharpness of the image and thus to evaluate the image quality of the code.)

说明：  自适应中值滤波器的滤波方式和传统的中值滤波器一样,都使用一个矩形区域的窗口Sxy,不同的是在滤波过程中,自适应滤波器会根据一定的设定条件改变(即增加)滤窗的大小,同时当判断滤窗中心的像素是噪声时,该值用中值代替,否则不改变其当前像素值,这样用滤波器的输出来替代像素(x,y)处(即目前滤窗中心的坐标)的值。(Adaptive Median Filter for filtering methods and the same as the traditional median filter, use a rectangular area of the window Sxy, different in the filtering process, the adaptive filter in on certain Presumed Conditions change (an increase of ) filter window size, while when the judge is the filter window center pixel noise, the median value is used instead of, or does not change its current pixel value, so that the output with a filter to replace the pixels (x, y) Office (that is, coordinates of the current filter window centered) values.)

双闭环调速控制系统MATLAB程序，可以用来实现双闭环调速系统控制。(DC control system)

该算法详细仿真了EKF、UKF以及PF三种方法，进行了对比，只需简单的调整参数就可以观察在不同条件下的滤波效果。(The algorithm detailed simulation of the EKF, UKF and PF three methods were compared, a simple adjustment of parameters can be observed under different conditions of the filtering effect.)
