how run crop_face.py to crop the images
Please anyone help me regarding using the python scripts provided by the opencv. I am working on face recognition in videos using opencv 2.4.8 and microsoft visual studio ultimate 2012. I have created a folder called images , and saved at desktop, containing two photos each of three subjects. Now I have got stuck with the problem of how to use the two python scripts create_csv.py and crop_face.py. Please guide me with a step by step procedure as I am new to it.
I suppose this link (http://docs.opencv.org/trunk/modules/contrib/doc/facerec/tutorial/facerec_video_recognition.html) is detailed enough.
