I am trying to implement the real-time face recognition using opencv and python.
Each time i open my detector it gets stuck and gives error, could please help ?
import cv2
import numpy as np
recognizer = cv2.face.createLBPHFaceRecognizer()
recognizer.load('trainner/trainner.yml')
cascadePath = "haarcascade_frontalface_default.xml"
faceCascade = cv2.CascadeClassifier(cascadePath);
cam = cv2.VideoCapture(0)
font = (cv2.FONT_HERSHEY_SIMPLEX, 1, 1, 0, 1, 1)
while True:
ret, im =cam.read()
gray=cv2.cvtColor(im,cv2.COLOR_BGR2GRAY)
faces=faceCascade.detectMultiScale(gray, 1.2,5)
for(x,y,w,h) in faces:
cv2.rectangle(im,(x,y),(x+w,y+h),(225,0,0),2)
Id, conf = recognizer.predict(gray[y:y+h,x:x+w])
if(conf<50):
if(Id==1):
Id="Anirban"
elif(Id==2):
Id="Sam"
else:
Id="Unknown"
cv2.cv.PutText(cv2.cv.fromarray(im),str(Id), (x,y+h),font, 255)
cv2.imshow('im',im)
if cv2.waitKey(10) & 0xFF==ord('q'):
break
cam.release()
cv2.destroyAllWindows()
The error:
TypeError Traceback (most recent call last)
in ()
16 for(x,y,w,h) in faces:
17 cv2.rectangle(im,(x,y),(x+w,y+h),(225,0,0),2)
---> 18 Id, conf = recognizer.predict(gray[y:y+h,x:x+w])
19 if(conf<50):
20 if(Id==1):
TypeError: 'int' object is not iterable
