Python-OpenCV实现二值图像孔洞填充

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：
