无法在OpenCV Python中使用标志? [英] Unable to use flags in OpenCV Python?

问题描述

我无法在OpenCV中使用标志.

I'm unable to use flags in OpenCV.

例如:

import cv2

image = cv2.imread('k.jpg',cv2.CV_LOAD_IMAGE_GRAYSCALE)

cv2.namedWindow('Pic',cv2.CV_WINDOW_NORMAL)

cv2.imshow('Pic', image)

cv2.waitKey()

在此程序中，我可以使用cv2.CV_LOAD_IMAGE_GRAYSCALE，但在这里不能使用namedWindow的标志.这给出了错误:

In this program I'm able to use cv2.CV_LOAD_IMAGE_GRAYSCALE but I'm not able to use flags for namedWindow here. This one gives error:

module has no attribute CV_WINDOW_NORMAL

推荐答案

只需简短更新:

从OpenCV 3.0开始，它们分别是cv2.IMREAD_GRAYSCALE和cv2.WINDOW_NORMAL(整个列表使用help(cv2)).

Since OpenCV 3.0, these are cv2.IMREAD_GRAYSCALE and cv2.WINDOW_NORMAL (use help(cv2) for the whole list).
