with using python, openCV and mediapipe I wrote the code below:

import mediapipe as mp
import cv2

# Initial MediaPipe hand detection
mp_hand = mp.solutions.hands
mp_drawing = mp.solutions.drawing_utils
hands = mp_hand.Hands(min_detection_confidence=0.8, min_tracking_confidence=0.5)

# Initial webcam read
cap = cv2.VideoCapture(0)
assert cap.isOpened(), "Camera not found"

while cap.isOpened():
    # Read img from webcam
    success, img = cap.read()
    if not success:
        break
    
    # Convert the image color from BGR to RGB
    img_rgb = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
    
    # Detect hand by MediaPipe
    results = hands.process(img_rgb)
    
    # Draw hand landmarks
    if results.multi_hand_landmarks:
        for hand_landmarks in results.multi_hand_landmarks:
            mp_drawing.draw_landmarks(img, hand_landmarks, mp_hand.HAND_CONNECTIONS)

    # Display results
    cv2.imshow('webcam', img)

    if cv2.waitKey(1) & 0xff == ord('q'):
        break

# Release resources
cap.release()
cv2.destroyAllWindows()

output:
enter image description here

I want to prevent this little vibration during detection. how can I do that?
