How to create CSV file in windows (face recognition) ?
Hi, I am new to python and open CV. I have at & t database and want to create a CSV so that I can train and run the face recognition code "http://docs.opencv.org/trunk/modules/contrib/doc/facerec/tutorial/facerec_video_recognition.html"
I am using windows, my question is, how to run this below python script in windows / call this function and create a CSV file, as per the given guidelines " simply call create_csv.py with the path to the folder, just like this and you could save the output: philipp@mango:~/facerec/data$ python create_csv.py "
I am unable to do this in windows, please help. Thanks!!!
!/usr/bin/env python
import sys import os.path
This is a tiny script to help you creating a CSV file from a face
database with a similar hierarchie:
#
philipp@mango:~/facerec/data/at$ tree

if __name__ == "__main__":
if len(sys.argv) != 2:
print "usage: create_csv <base_path>"
sys.exit(1)
BASE_PATH=sys.argv[1]
SEPARATOR=";"
label = 0
for dirname, dirnames, filenames in os.walk(BASE_PATH):
for subdirname in dirnames:
subject_path = os.path.join(dirname, subdirname)
for filename in os.listdir(subject_path):
abs_path = "%s/%s" % (subject_path, filename)
print "%s%s%d" % (abs_path, SEPARATOR, label)
label = label + 1
so, how did you call it and what went wrong ?
i have python 2.7 installed in the system, when I run this script I get
>>> ================================ RESTART ================================ >>> usage: create_csv <base_path> >>>
and then program terminates.
if your att faces are in d:/ema/att, you'd call it like this:
python create_csv.py d:/ema/att
(well, this will print the filenames/labels to console output, so you want to redirect that into a textfile:)
python create_csv.py d:/ema/att > att_faces.csv
Where should I insert this command " python create_csv.py d:/ema/att " in the GUI of the python or in windows command line(cmd.exe) ?
ah, try from cmdline first
Thanks!!! Its working now.
How do you do this in the cmdline? i tried some thing like " python create_csv.py c;/location/att_faces " but it just gives me ' python ' is not recognized as an internal or external command?
@Raymund_Ocaba if you haven't got python installed, you can't run python scripts. full-stop.
just get creative - the required csv file jus consists of lines like:
full_path_to_image semicolon label_id
(really, there's no magic involved here)
i did install python 3.3 and still won't recognized it
it's probably expecting python2.7 (but such a simple thing should not make any difference, imho)
no idea now, sorry
