我无法在 openCV 中运行凸轮移位演示

我在VS2010中安装了openCV2.3.1。我可以在openCV中读取图像而没有任何错误。但是当我运行camshiftdemo从文件夹打开/samples/cpp。显示此错误。

当我注释这行//RotatedRect trackBox = CamShift(backproj, trackWindow，TermCriteria(CV_TERMCRIT_EPS | CV_TERMCRIT_ITER, 10,1));没有错误

在我的另一个代码中，它显示了这样的错误。这是我测试meanshift

int main()
{
    // Read reference image
    cv::Mat image= cv::imread("Desert.jpg");
    if (!image.data)
        return 0; 
    // Define ROI
    cv::Mat imageROI= image(cv::Rect(110,260,35,40));
    cv::rectangle(image, cv::Rect(110,260,35,40),cv::Scalar(0,0,255));
    // Display image
    cv::namedWindow("Image");
    cv::imshow("Image",image);
    // Get the Hue histogram
    int minSat=65;
    ColorHistogram hc;
    //cv::MatND colorhist= hc.getHueHistogram(imageROI,minSat);
    ObjectFinder finder;
    //finder.setHistogram(colorhist);
    finder.setThreshold(0.2f);
    // Convert to HSV space
    cv::Mat hsv;
    cv::cvtColor(image, hsv, CV_BGR2HSV);
    // Split the image
    vector<cv::Mat> v;
    cv::split(hsv,v);
    // Eliminate pixels with low saturation
    cv::threshold(v[1],v[1],minSat,255,cv::THRESH_BINARY);
    cv::namedWindow("Saturation");
    cv::imshow("Saturation",v[1]);
    // Get back-projection of hue histogram
    int ch[1]={0};
    cv::Mat result= finder.find(hsv,0.0f,180.0f,ch,1);
    cv::namedWindow("Result Hue");
    cv::imshow("Result Hue",result);
    cv::bitwise_and(result,v[1],result);
    cv::namedWindow("Result Hue and");
    cv::imshow("Result Hue and",result);
    // Second image
    image= cv::imread("Desert.jpg");
    // Display image
    cv::namedWindow("Image 2");
    cv::imshow("Image 2",image);
    // Convert to HSV space
    cv::cvtColor(image, hsv, CV_BGR2HSV);
    // Split the image
    cv::split(hsv,v);
    // Eliminate pixels with low saturation
    cv::threshold(v[1],v[1],minSat,255,cv::THRESH_BINARY);
    cv::namedWindow("Saturation");
    cv::imshow("Saturation",v[1]);
    // Get back-projection of hue histogram
    result= finder.find(hsv,0.0f,180.0f,ch,1);
    cv::namedWindow("Result Hue");
    cv::imshow("Result Hue",result);
    // Eliminate low stauration pixels
    cv::bitwise_and(result,v[1],result);
    cv::namedWindow("Result Hue and");
    cv::imshow("Result Hue and",result);
    // Get back-projection of hue histogram
    finder.setThreshold(-1.0f);
    result= finder.find(hsv,0.0f,180.0f,ch,1);
    cv::bitwise_and(result,v[1],result);
    cv::namedWindow("Result Hue and raw");
    cv::imshow("Result Hue and raw",result);
    cv::Rect rect(110,260,35,40);
    cv::rectangle(image, rect, cv::Scalar(0,0,255));
    cv::TermCriteria criteria(cv::TermCriteria::MAX_ITER,10,0.01);
//  cout << "meanshift= " << cv::meanShift(result,rect,criteria) << endl;
    cv::rectangle(image, rect, cv::Scalar(0,255,0));
    // Display image
    cv::namedWindow("Image 2 result");
    cv::imshow("Image 2 result",image);
    cv::waitKey();
    return 0;
}

当我运行这段代码时，它显示这个错误。
