基于vc++与opencv实现的视频图像Hu矩计算，可以作为运动检测的一个模块。运行时需要有一台usb摄像机才能正确执行。,Based on vc++ with opencv video images to achieve the calculation of Hu moments, can be used as a motion detection module. Run-time need to have a usb camera to the correct implementation.

USB摄像头内的出现的移动物体的检测。需要使用.net framework。内附代码和演示程序(Detection of moving objects within the USB camera. You need to use.Net framework. Enclosing code and demonstration program)
