代码

import cv2
import numpy as np
img = cv2.imread('1.jpg',0)
a = cv2.resize(img,(300,500))
binary = cv2.threshold(a,250,250,0)[1]
k = cv2.getStructuringElement(cv2.MORPH_RECT,(20,1))
blackhat = cv2.morphologyEx(a,cv2.MORPH_BLACKHAT,k)
cv2.imshow('blackhat',255-blackhat)
cv2.imshow('binary',binary)
cv2.imshow('img',img)
cv2.waitKey()
cv2.destroyAllWindows()

以上就是今天要讲的内容，本文仅仅简单介绍了OpenCv中的形态学操作的使用。
