python opencv cv2在图片中画mask掩膜

import cv2import numpy as npfrom PIL import Imageimport matplotlib.pyplot as pltmask_threth = 50img = cv2.imread('./1.jpg') #自己qq截图一张图片就行，要大于下面的坐标点# binary maskcoordinates = []coordinate1 = [[[40, 135], [168,132], [164,330], [2,328]]]coordinate2 = [[[300, 300], [600,300], [600,600], [300,600]]]coordinate1 = np.array(coordinate1)coordinate2 = np.array(coordinate2)coordinates.append(coordinate1)coordinates.append(coordinate2)mask = np.zeros(img.shape[:2], dtype=np.int8)mask = cv2.fillPoly(mask, coordinates, 255)cv2.imwrite('./mask1.png', mask)bbox_mask = maskcolor_mask = np.array([0, 0, 255], dtype=np.uint8)bbox_mask = bbox_mask.astype(np.bool)# cv2.imwrite('./bbox_mask.png', bbox_mask)img[bbox_mask] = img[bbox_mask] + color_mask * 0.5img = img[:,:,::-1]plt.imshow(img)# plt.savefig('./result.png')plt.show()

结果如图所示：
