import numpy as np
import os
import cv2

image_file = r"C:\\Users\\fut\\Desktop\\test2.jpg"
img = cv2.imread(image_file)
black_lower = np.array([0, 0, 0])
black_upper = np.array([180, 255, 46])
img_hsv = cv2.cvtColor(img, cv2.COLOR_BGR2HSV)
mask = cv2.inRange(img_hsv, black_lower, black_upper)
cv2.imshow('result',mask)
cv2.waitKey(0)
