cap = cv2.VideoCapture(0)

while True:
    ret, frame = cap.read()
    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
    faces = face_cascade.detectMultiScale(gray, 1.1, 4)

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

    cv2.imshow('frame', frame)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

cap.release()
cv2.destroyAllWindows()

    if num_objects > 0:
        # Proceed only if at least one object detected
        confidence_threshold = 0.5 / num_objects
        boxes = [box for box in boxes if confidences[boxes.index(box)] > confidence_threshold]
        confidences = [confidences[boxes.index(box)] for box in boxes]

        # Create two lists to contain filtered bounding boxes
