C++与OpenCV同时批量处理图像数据

在单张调试图像效果时，可以将算法单次运行，以调试效果。但是，如果图像多到几万张时，我们就需要掌握批量处理图像的方法。在前辈的基础上做了微调。

string gallery_path = "D:\\1.jpg";//批量处理图像的路径
string probe_path = "D:\\……";//处理之后需要批量存入的路径
vector gallery_folders = listDir(gallery_path);
for (int g = 0; g < gallery_folders.size(); g++)
    {
        //vector image_list = listFile(gallery_path + "\\" + gallery_folders.at(g), "png");
        vector image_list = listFile( gallery_folders.at(g), "png");
        for (int f = 0; f < image_list.size(); f++)
        {
            int m = image_list.size();
            cout << m << endl;
            /*cout << gallery_path + "\\" + gallery_folders.at(g) + "\\" + image_list.at(f) << endl;*/
            string ga = gallery_folders.at(g);
            cout << "gallery_folders.at(g):  " << ga << endl;
            string ss = image_list.at(f);//this is picture number
            cout << "image_list.at(f)" << ss << endl;
            //string filename = gallery_path + "\\" + gallery_folders.at(g) + "\\" + image_list.at(f);
            string filename = gallery_folders.at(g) ; 
            Mat srcImage, grayImage;
            srcImage = imread(filename);
            //srcImage.convertTo(srcImage, CV_16UC1);
            //Show_Function(srcImage);
            //Show_Function1(srcImage, image_list.at(f));
            string filename_end = probe_path+"\\" + image_list.at(f);
            imwrite(filename_end, OutputImage);//grayImage    dst img1

        }
    }
