问题描述

我在ubuntu 12.04上使用opencv 2.4.7.我正在用python编程，运行此脚本时出现问题:

I'm using opencv 2.4.7 on ubuntu 12.04. I'm programming with python and I have a problem when i run this script:

import cv2

img = cv2.imread('347620923614738322_233985812.jpg')
cv2.namedWindow("window")
cv2.imshow("window", img)
cv2.waitKey(0)

问题是关闭图像时脚本不会停止.我搜索了有关waitKey的信息，发现使用cv2.waitKey(0)是正确的.

The problem is that the script doesn't stop when I close the image. I searched information about waitKey and I found that using cv2.waitKey(0) is correct.

我不明白，问题出在哪里?

import numpy as np
import cv2

# Load an color image in grayscale
img = cv2.imread('Lena.tiff',0)
WINDOW_NAME = 'Image de Lena'
cv2.namedWindow(WINDOW_NAME, cv2.CV_WINDOW_AUTOSIZE)
cv2.startWindowThread()

# Display an image
cv2.imshow(WINDOW_NAME,img)
cv2.waitKey(0) 


cv2.destroyAllWindows()
