opencv遍历文件夹

#include <opencv2opencv.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;
}
