文章参考于张平编著《OpenCV算法精解-基于Python与C++》
#coding=utf-8
import cv2
import  sys
if __name__=='__main__':
if len(sys.argv)>1:
image=cv2.imread(sys.argv[1],cv2.CV_LOAD_IMAGE_UNCHANGED)
else:
print('can not open the image')
cv2.imshow('img',image)
cv2.waitKey(0)
cv2.destroyAllWindows()
调用代码：~/PycharmProjects/OpenCV$ python img_show.py tim2.jpg
