代码如下：
import cv2
import numpy as np
def FillHole(mask):
contours, hierarchy = cv2.findContours(mask, cv2.RETR_TREE, cv2.CHAIN_APPROX_SIMPLE)
len_contour = len(contours)
contour_list = []
for i in range(len_contour):
drawing = np.zeros_like(mask, np.uint8) # create a black image
img_contour = cv2.drawContours(drawing, contours, i, (255, 255, 255), -1)
contour_list.append(img_contour)
out = sum(contour_list)
return out
if __name__ == \'__main__\':
mask_in = cv2.imread(\'C:\\Users\\admin\\Desktop\\mask_in.tif\', 0)
mask_out = FillHole(mask_in)
cv2.imwrite(\'C:\\Users\\admin\\Desktop\\mask_out.tif\', mask_out)
效果如下：
