如何在opencv-python的特定背景颜色上裁剪图像中的对象？

import cv2
import numpy as np

image = cv2.imread('image.jpg')
hsv_image = cv2.cvtColor(image, cv2.COLOR_BGR2HSV)

lower_color = np.array([H_min, S_min, V_min])
upper_color = np.array([H_max, S_max, V_max])

mask = cv2.inRange(hsv_image, lower_color, upper_color)

kernel = np.ones((5, 5), np.uint8)
mask = cv2.morphologyEx(mask, cv2.MORPH_OPEN, kernel)

contours, _ = cv2.findContours(mask, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)

for contour in contours:
    x, y, w, h = cv2.boundingRect(contour)
    object_roi = image[y:y+h, x:x+w]
    cv2.imshow('Object ROI', object_roi)
    cv2.waitKey(0)
