cv2.imread flags not found

Question

I recently started working with openCV and python and decided to analyze some sample code to get an idea of how things are done.

However, the sample code I found, ke

Answer 1

OpenCV 3.0 came with some namespace changes, and this might be one of them. The function reference given in the other answer is for OpenCV 2.4.11, and unfortunately there are significant renamings, including enumerated parameters.

According to the OpenCV 3.0 Example here, the correct parameter is cv2.IMREAD_COLOR.

According to the OpenCV 3.0 Reference Manual for C, CV_LOAD_IMAGE_COLOR is still there.

And my conclusion from the above resources and here, they changed it in OpenCV 3.0 python implementation.

For now, the best to use seems like the following:

img = cv2.imread("link_to_your_file/file.jpg", cv2.IMREAD_COLOR) 

Answer 2

have you tried this?

import cv2
import sys
import numpy as np


cv2.CV_LOAD_IMAGE_COLOR = 1 # set flag to 1 to give colour image
#cv2.CV_LOAD_IMAGE_COLOR = 0 # set flag to 0 to give a grayscale one


img = cv2.imread("link_to_your_file/file.jpg", cv2.CV_LOAD_IMAGE_COLOR) 


cv2.namedWindow('Display Window') ## create window for display
cv2.imshow('Display Window', img) ## Show image in the window
print ("size of image: "), img.shape ## print size of image
cv2.waitKey(0) ## Wait for keystroke
cv2.destroyAllWindows() ## Destroy all windows
