OpenCV implement Traverse folder all files

OPENCV has a class directory that implements all the files that traverse the folder, which includes 3 member functions: (1), Getlistfiles: Iterates through all the files under the specified folder, excludes folders within the specified folder, (2), Getlistfolders: Traverse all folders under the specified folder, excluding files under the specified folder, (3), GETLISTFILESR: Iterates through all files under the specified folder, including folders within the specified folder.

To use the directory class, you need to include the CONTRIB.HPP header file, the implementation of this class in the contrib module.

The following is the test code:

CV::D irectory Dir;string path1 = "E:/data/image"; string exten1 = "*.bmp";//"*" bool addPath1 = false;//true;vector<string> filenames = dir. Getlistfiles (path1, Exten1, addPath1);cout<< "file names:" <<endl;for (int i = 0; I < filenames.size (); i++) cout<<filenames[i]<<endl;string path2 = "E:/data/image"; string exten2 = "*";//"image*";//"*" bool AddPath2 = true;//falsevector<string> Foldernames = dir. Getlistfolders (path2, Exten2, addPath2);cout<< "folder names:" <<endl;for (int i = 0; I < foldernames.size (); i++) cout<<foldernames[i]<<endl;string path3 = "E:/data/image"; string exten3 = "*"; bool AddPath3 = true;// falsevector<string> allfilenames = dir. GETLISTFILESR (Path3, Exten3, AddPath3);cout<< "All file names:" <<endl;for (int i = 0; I < allfilenames.size (); i++) Cout<<allfilenames[i]<<endl;
