opencv3.x遍历文件夹读取图片

#include <opencv2\opencv.hpp>#include <iostream>using namespace std;using namespace cv;int main(){    //用void glob(String pattern, std::vector<String>& 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    //pattern要绝对路径 其它测试有问题    string pattern = "D:/Acodes/data/*.jpg";    //cout << pattern << endl;    vector<Mat> images;    // 必须cv的String    vector<String> fn;    glob(pattern, fn, false);    size_t count = fn.size();    cout << count << endl;    for (int i = 0; i < count; i++){        images.push_back(imread(fn[i]));        imshow("jaj", images[i]);        waitKey(10);    }    return 1;}
