opencv+python二值图象反色操作，为什么运行一直转圈圈

Question

import cv2
image = cv2.imread ("initial.png", 0)
cv2.imshow('initial',image)
cv2.waitKey(0)
ret,image1 = cv2.threshold(image,80,255,cv2.THRESH_BINARY)
cv2.imshow('grayscale',image1)
cv2.waitKey(0)
image2 = cv2.bitwise_not(image1)        
cv2.imshow('colorReverse',image2)

Answer 1

代码运行没有问题的，最后加上一行cv2.waitKey(0)
