OpenCV自带方法遍历目录下文件

Directory定义于contrib.hpp（v2.0以上），定义很简单就三个函数：

class CV_EXPORTS Directory  {  public:      static std::vector<std::string> GetListFiles  ( const std::string& path, const std::string & exten = "*", bool addPath = true );      static std::vector<std::string> GetListFilesR ( const std::string& path, const std::string & exten = "*", bool addPath = true );      static std::vector<std::string> GetListFolders( const std::string& path, const std::string & exten = "*", bool addPath = true );  };

使用起来也很简单：

// Use opencv built-in methods to get image filenames of specified folder.    #include <iostream>  using namespace std;    #include <opencv2\opencv.hpp>  #include <opencv2\highgui\highgui.hpp>  #include <opencv2\contrib\contrib.hpp>  using namespace cv;    int main(int argc, char* argv[])  {      string dir_path = "D:\\opencv_pic\\test\\";      Directory dir;      vector<string> fileNames = dir.GetListFiles(dir_path, "*.jpg", false);        for(int i = 0; i < fileNames.size(); i++)      {          //get image name          string fileName = fileNames[i];          string fileFullName = dir_path + fileName;          cout<<"File name:"<<fileName<<endl;          cout<<"Full path:"<<fileFullName<<endl;            //load image          IplImage* srcImg = cvLoadImage(fileFullName.c_str(), -1);          cvShowImage("src", srcImg);          cvWaitKey(0);      }      return 0;  }
