import cv2

while True:
# Capture frame-by-frame
ret, frame = cap.read()
# Convert the frame to grayscale (face detection works better in grayscale)

# Detect faces in the frame
faces = face_cascade.detectMultiScale(gray, scaleFactor=1.1, minNeighbors=5, minSize=(30, 30))
# Draw rectangles around the faces
for (x, y, w, h) in faces:

# Display the resulting frame

# Break the loop if 'q' is pressed
if cv2.waitKey(1) & 0xFF == ord('q'):

# Release the capture and close any open windows
