opencv图像处理学习（七十五）——glob遍历文件夹下的所有图片

用void glob(String pattern, std::vector& result, bool recursive = false);
//当recursive为false时，仅仅遍历指定文件夹内符合模式的文件，当recursive为true时，会同时遍历指定文件夹的子文件夹

#include 
#include 
using namespace std;
using namespace cv;
int main()
{
    //要绝对路径
    string path = "D:\\data\\*.bmp";
    cout << path << endl;
    vector images;
    // 必须cv的String
    vector fn;
    glob(path, fn, false);
    size_t count = fn.size();
    cout << count << endl;
    for (int i = 0; i < count; i++)
    {
        images.push_back(imread(fn[i]));
        imshow("pic", images[i]);
        waitKey(10);
    }
    return 0;
}
