d I have never worked on python, please if anyone could tell me "how" and "where" to call create_csv.py and crop_face.py. I have installed python 2.7 and PIL-1.1.7.win-amd64-py2.7. I have read the documentation of face recognition in video using opencv 2.4.8, on which i am working, but there is no syntax provided of how to call these python scripts. Please help.
