Code taught in Face Detection using HaarCascade video is not running

#1

THIS IS THE CODE I HAVE WRITTEN BUT IT IS NOT RUNNING. WHEN I RUN THE CODE, A BLANK WINDOW POPS UP (ITS TITLE SHOWS A PATH OF .EXE FILE IN C DRIVE) AND AUTOMATICALLY CLOSES. PLEASE HELP.

import cv2
cap=cv2.VideoCapture(0)
face_cascade = cv2,CascadeClassifier(‘haarcascade_frontalface_alt.xml’)

while True:
ret,frame = cap.read()
gray_frame = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
if ret==False:
continue

faces = face_cascade.detectMultiScale(gray_frame, 1.3, 5)

for (x,y,w,h) in faces:
    cv2.rectangle(frame, (x,y), (x+w,y+h), (255,0,0), 2)

cv2.imshow("Video Frame", frame)

key_pressed = cv2.waitKey(1) & 0xFF

if key_pressed == ord('q'):
    break

cap.release()
cv2.destroyAllWindows()

Hello @vinay86048, cv2 library is working or not ?? And have you created the file ‘haarcascade_frontalface_alt.xml’ file in the same folder or different ??

#3

cv2 is working fine. It worked in the code in which I had to open default webcam and capture video streams. I had downloaded the haarcascade file and copied it in the same folder in which python file is created.

#4

in this line cv2. must be there I think you put comma ‘,’
