Opencv3.x版本中glob递归遍历文件夹图像

#include 
#include 
using namespace std;
using namespace cv;
int main() {
	//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
	//pattern要绝对路径 其它测试有问题
	string pattern = "C:\\Users\\wangzhenlin\\Pictures\\Camera Roll\\*.PNG";
	//cout << pattern << endl;
	vector images;
	// 必须cv的String
	vector fn;
	glob(pattern, fn, true);
	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(100);
	}
	return 1;
}

二

#include 
#include 
using namespace std;
using namespace cv;

int main() {
	//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

	//pattern要绝对路径 其它测试有问题
	string pattern = "C:\\Users\\wangzhenlin\\Desktop\\新建文件夹 (3)\\样本\\*.jpg";
	//cout << pattern << endl;
	vector images;
	// 必须cv的String
	vector fn;
	glob(pattern, fn, true);
	size_t count = fn.size();
	cout << count << endl;//162
	for (int i = 0; i < count; i++) {
		images.push_back(imread(fn[i]));
		//imshow("jaj", images[i]);
		string s = "C:\\Users\\wangzhenlin\\Desktop\\新建文件夹 (3)\\样本\\" + to_string(i) + ".jpg";
		//string s = to_string(i);
		imwrite(s, images[i]);
		waitKey(100);
	}
	getchar();
	return 1;
