Hi Berak, are you still there?

Then you said the program uses the 1st image from the folder for testing, which folder? root or the 1st image in the person1 folder (which is inside the folder images), that are actually my data? If it happens so, what do I need to change in the program to make it to user the image captured01.jpg inside root folder, which was taken by a webcam?

so my program facerec_demo.py is the the folder 'root' and inside this folder I have other two folders 'images' and 'resultados'. Inside 'images' I have other two folders, 'person1' and 'person2' where the images really are, so I thought I needed to change 'None' to 'resultado', but when I do that the program says resultado isn't defined

File "facerec_demo.py", line 58, in <module>
    out_dir = resultado
NameError: name 'resultado' is not defined

but when I leave None it prints USAGE: facerec_demo.py </images> [</resultado>]

it means the program ends in the 'if'

if len(sys.argv) < 2: print "USAGE: facerec_demo.py </images> [</resultado>]" sys.exit()

what does mean len(sys.argv) < 2?

Oh ok, so it save the images as teste.png.

1) opencv tutorial suggest to use pgm, then I need to convert my pictures to this format, right? 2) I'm running my program from ssh terminal on my macbook. Should I not replace the sys.argv[1] by the name of the folder where the images are? (in this case its name is 'images'), since it's an atribute of the function 'read_images'. 'resultado' is a folder where I want to save the picture after all process. In the original code phillip wrote

if __name__ == "__main__":
   # This is where we write the images, if an output_dir is given
   # in command line:
   out_dir = None
   # You'll need at least a path to your image data

Hi berak. I was trying to implemente the code you mentioned, but I find a problem in the lines: from facerec.feature import Fisherfaces and from ... import ... File "13mayreconhecimento.py", line 4 import Fisherfaces ^ IndentationError: unexpected indent

do you know what it means?

Hi everybody.

I have the image IoT DevKit installed in my Galileo platform and I would like to write a program, it can be in python to do face recognition. I want my program works like that: There will be two folders: resources and results. Inside of resources I want another two folders (person1 and person2) and inside both I want to include pictures .jpg of faces. There will be a webcam connected in Galileo. So I will stand in front of the camera in order it takes a picture of my face. I click in a button in my Galileo, then it will take a picture and verify if my face is inside of person1 or person2 folders and I want the program save the picture in results and give me a signal the person is in the system or not, for example printing in SSH terminal a message saying that and later I want to send this signal as 0 or 1 in an output to use in external circuits. The only program I have is to do face detection, take a look:

import numpy as np
import cv2

# it starts the caputre
capture = cv2.VideoCapture(0)
# take the last received frame
ret,img = capture.read()
# save as pic.jpg

cv2.imwrite('pic.jpg', img)


capture.release()


face_cascade = cv2.CascadeClassifier('/home/root/haarcascade_frontalface_default.xml')
eye_cascade = cv2.CascadeClassifier('/home/root/haarcascade_eye.xml')

img = cv2.imread('pic.jpg')
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
faces = face_cascade.detectMultiScale(gray, 1.3, 5)
for (x,y,w,h) in faces:
        cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2)
        roi_gray = gray[y:y+h, x:x+w]
        roi_color = img[y:y+h, x:x+w]
        eyes = eye_cascade.detectMultiScale(roi_gray)
        for (ex,ey,ew,eh) in eyes:
         cv2.rectangle(roi_color,(ex,ey),(ex+ew,ey+eh),(0,255,0),2)

cv2.imwrite('img.png', img)

This program also design squares on the eyes, mouth and face, so I have done the detection, but I still need the recognition. That's the first time I work with embedded systems and Galileo platform and all program I find is for linux in desktops. Thank you.
