使用Matlab设计一个简单的滤波器小程序-Use Matlab to design a simple filter applet

利用转换公式将真彩图像转换为灰度图像。将灰度图像的每一个像素点对应一个元素保存在一个矩阵中。然后利用帧差法进行图像差分处理，从而提取出运动目标。对差分后的图像二值化处理，用最大类间方差分割法遍历求取最优阈值。使其作为基准，区分差分图像的背景元素和目标元素。最后用matlab进行编程使目标信息高亮显示在屏幕上。(The true color image is converted to gray image by transformation formula. Each pixel of a grayscale image is stored in a matrix corresponding to one element. Then the frame difference method is applied to image difference processing to extract moving targets. After the two valued processing of the differential image, the optimal threshold is obtained by traversing the maximum variance between classes. It is used as a benchmark to distinguish the background and target elements of the differential image. Finally, Matlab is programmed to highlight the target information on the screen.)
