python + opnencv实现图像孔洞填充

import cv2import numpy as np

path = "_holefill.jpg"img = cv2.imread(path)gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)#转换成灰度图ret, thresh = cv2.threshold(gray, 50, 250, cv2.THRESH_BINARY_INV)#灰度图转换成二值图像thresh_not = cv2.bitwise_not(thresh)#二值图像的补集

kernel = cv2.getStructuringElement(cv2.MORPH_ELLIPSE, (3,3))#3×3结构元

"""构建阵列F，并将thresh_not边界值写入F"""F = np.zeros(thresh.shape, np.uint8)F[:, 0] = thresh_not[:, 0]F[:, -1] = thresh_not[:, -1]F[0, :] = thresh_not[0, :]F[-1, :] = thresh_not[-1, :]

"""循环迭代，对F进行膨胀操作，结果与thresh_not执行and操作"""for i in range(200):    F_dilation = cv2.dilate(F, kernel, iterations=1)    F = cv2.bitwise_and(F_dilation, thresh_not)

result = cv2.bitwise_not(F)#对结果执行not

#显示结果cv2.imshow(‘p‘,result)cv2.imshow(‘r‘,thresh)cv2.waitKey(0)
