c++ - 如何在 OpenCV 中读取 ".jpg"图像序列？

Question

我目前正在 OpenCV 中尝试 BackgroundSubtractorMOG 和 BackgroundSubtractorMOG2，我想尝试将 jpg 图像序列作为我的帧的来源

frame = imread("C:\images\001-capture.jpg");
    if(!frame.data){
    //error in opening the first image
    cerr << "Unable to open first image frame: " << fistFrameFilename << endl;
    //exit(EXIT_FAILURE);
}

也因为当我使用 VideoCapture 访问我的 .avi 视频剪辑时出现错误。

VideoCapture capture("C:\movie1.avi");
if(!capture.isOpened()){
    //error in opening the video input
    cerr << "Unable to open video file: " << videoFilename << endl;
    exit(EXIT_FAILURE);
}
//read input data. ESC or 'q' for quitting
while( (char)keyboard != 'q' && (char)keyboard != 27 ){
//read the current frame
if(!capture.read(frame)) {
  cerr << "Unable to read next frame." << endl;
  cerr << "Exiting..." << endl;
  exit(EXIT_FAILURE);
}

Answer 1

• 尝试 VideoCapture 捕获("C:/movie1.avi");//使用单个“/”或双“\”!

• 如果编号正确，VideoCapture 也可以读取图像序列:

  VideoCapture 捕获("C:/images/%3d-capture.jpg");//顺便说一句，与上面相同的斜杠概率
