OpenCV：图像开闭运算

import cv2
import numpy as np

#读取图片
src = cv2.imread('edge2.jpg', cv2.IMREAD_UNCHANGED)

#设置卷积核
kernel = np.ones((3,3), np.uint8)

#图像闭运算
result = cv2.morphologyEx(src, cv2.MORPH_CLOSE, kernel)

# 图像开运算
# result = cv2.morphologyEx(result, cv2.MORPH_OPEN, kernel)
#显示图像
cv2.imshow("src", src)
cv2.imshow("result", result)

#等待显示
cv2.waitKey(0)
cv2.destroyAllWindows()
