Question

我有一个项目，其中一部分将视频处理为一批图像。我在网上找到了一段代码，可以帮助我处理一批图像（如下图所示）

string Img_seq[] = {"flying_plane"};

int size_of_Img_seq = sizeof(Img_seq) / sizeof(Img_seq[0]);
    imgpath = argv[1];
    if (argc >= 3)
    {
        TrackingResPath = argv[2];


    cout << "The image path is: " << imgpath << endl;
    int Seg_num = 1; //for OPE
    for (int j = 0; j < size_of_Img_seq; ++j)
    {
        folder = imgpath + Img_seq[j] + "/*.jpg";
        string imgInFormat, imgOutFormat, imgOutFormat1, imgOutFormat2; 
        ofstream outBB;
        imgInFormat = imgpath + Img_seq[j] + "/%05d.jpg";

        if (argc >= 3)
        {
            //add process here
        }
        }


        // get the total number of images in folder
        glob(folder, filenames);

        int Frames_per_seg = filenames.size(); // for OPE
        cout << "Frames_per_seg = " << Frames_per_seg << endl;

        for (int k = 1; k <= Seg_num; ++k)
        {
            sprintf(imgInPath, imgInFormat.c_str(), startFrame);// read image path
            sprintf(imgOutPath, imgOutFormat.c_str(), startFrame);
      }

我需要使用此过程来处理来自目录或网络摄像头的视频。我尝试了下面提供的一种方法，但它会吐出错误

VideoCapture capture(videoFilename);
    if(!capture.isOpened()){
        cerr << "Unable to open video file:" << videoFilename << endl;
        exit(EXIT_FAILURE);
    }

    while( (char)keyboard != 'q' && (char)keyboard != 27){
        if(!capture.read(frame)){
            cerr << "Unable to read next frame" << endl;
            cerr << "Exiting" << endl;
            exit(EXIT_FAILURE);
        }}
        stringstream ss;
        rectangle(frame, cv::Point(10, 2), cv::Point(100, 20),
            cv::Scalar(255, 255, 255), -1);
        ss << capture.get(CV_CAP_PROP_POS_FRAMES);
        string Img_seq[] = ss.str();
        keyboard = waitKey( 30 );

这些错误基本上是由于上述两个代码之间的Img_seq[]未正确链接。

任何人都可以帮助我了解如何将视频用于批处理逻辑。
