Face Recognition -Generating Selfie Training data

#1

import numpy
import cv2

#int Cam
cap=cv2.VideoCapture(0)

#facedetection

face_cascade=cv2.CascadeClassifier(“haarcascade_frontalface_alt.xml”)
skip=0

while True:
ret,frame=cap.read()

if ret==False:
    continue
    
cv2.imshow("Frame",frame)
faces=face_cascade.detectMultiScale(frame,1.3,5)
print(faces)

#Store every 10th face
if(skip%10==0):
    break


key_pressed=cv2.waitKey(1) & 0xFF
if key_pressed==ord("q"):
    break

cap.release() # release the device

cap.destroyAllWindows()

In the above code I am gettting below error.

PS C:\Users\abhis\images> python face_data_collect.py
()
Traceback (most recent call last):
File “face_data_collect.py”, line 34, in
[ W cap.destroyAllWindows()
AttributeError: ‘cv2.VideoCapture’ object has no attribute ‘destroyAllWindows’
ARN:1] global C:\projects\opencv-python\opencv\modules\videoio\src\cap_msmf.cpp (436) `anonymous-namespace’::SourceReaderCB::~SourceReaderCB terminating async callback

It will be great help if you can help me figure out where i have done the error as I am unable to detect it.

Thank you.

hey @abhishekkundu86 ,
it should be cv2.destroyAllWindows().

Try this.
I hope this works.

Thank You :slightly_smiling_face:.
