+bbox in `face.txt` indicate the face region. You can turn on data augment which will flip the face, but you also need to give **symmetric landmarks index** for flip operation. If bbox is out of range of the original image, the program will fill the rest region with black.
 
 `background.txt` is much more simpler. Every line indicates where the background image in the file system.
