Opencvフォルダの画像を読み込む

http://blog.csdn.net/yang6464158/article/details/41622711 http://jingyan.baidu.com/article/656db918a7e848e381249c0e.htmlOpencvでフォルダの図を読み取ることは重要な仕事であり、特にシーケンス画像のセットであり、各画像を操作します.
方法1,filename,sprintf_s,imread

    char filename[100];
    Mat srcImage, dstImage;

    for (unsigned int i = 0; i < 100; i++)
    {
        sprintf_s(filename, "E://imageseries//bw_%04d.png", i);
        srcImage = imread(filename, 0);//         
    if (!srcImage.data){ printf("error!
"); return false; }
        imshow("image", srcImage);
        waitKey(1000);
...
//           ，         
sprintf__s(filename, "E://imageseries//after//bw_%04d.png", i);
imwrite(filename,dstImage)

}

方法二、VideoCapture sequence用

    string first_file = "E://imageseries//bw_%04d.png";
    VideoCapture sequence(first_file);

    if (!sequence.isOpened())
    {
        cerr << "Failed to open the image sequence!
" << endl;
        return 1;
    }
    Mat image;
    namedWindow("Image sequence", 1);
    for (;;){
        sequence >> image;
        if (image.empty())
        {
            cout << "End of Sequence" << endl;
            break;
        }
        imshow("Image sequence", image);
        waitKey(300);
    }

方法3:string src_image_name = “F:\imageseries\before\”; string src_image_name_after = “F:\imageseries\after\”; string src_image_name1 = src_image_name; char num[3], num1[4] = “1 (“, num2[6] = “).png”; string num3 = “.png”; for (i = 1; i <= 3; i++) { itoa(i, num, 10); src_image_name += num1; src_image_name += num; src_image_name += num2; cout << src_image_name << endl; src = imread(src_image_name, 1); imshow(src_image_name, src); }
