运动物体的检测

1，视频输入输出相关教程

#include <stdio.h>
#include <opencv2\opencv.hpp>

using namespace std;
using namespace cv;

int main()
{
    VideoCapture cap(0); //
    if (cap.isOpened())
        cout << "camera is opened "<< endl;
    else
        cout << "camera is not opende" <<endl;

    bool stop = false;
    Mat frame;

    cap.set(CV_CAP_PROP_FRAME_HEIGHT, 480);
    cap.set(CV_CAP_PROP_FRAME_WIDTH, 640);
    cap.set(CV_CAP_PROP_FPS, 30.0);

    //VideoWriter writer("test0.avi", CV_FOURCC('M', 'J', 'P', 'G'), 30, Size(640,480), true);
    for(;;)
    {
        cap >> frame;
        imshow("camera0", frame);

        char c = (char) waitKey(50);
        if (c == 27) break;
    }

/*    Mat grayim(600, 800, CV_8UC1);
    Mat colorim(600, 800, CV_8UC3);

    grayim = imread("E:\\会务系统开发\\Module\\opencv_door\\Debug\\ceshi.jpg");

    imshow("grayim", grayim);

    waitKey(0);
    */
    return 0;
}

2， 特征提取。因为我要追踪的物体没有特征，所以需要自己去人为的创造特征。
