What is the cv2.cv replacement in OpenCV3?

Question

I\'m using OpenCV3, and with the python bindings there is no cv2.cv module:

In [1]: import cv2

In [2]: from cv2 import cv
---------------------         


        

Answer 1

From OpenCV 2.X OpenCV 3.0 a few things changed.

Specifically:

• cv2.cv doesn't exists in OpenCV 3.0. Use simply cv2.
• some defines changed, e.g. CV_BGR2HSV is now COLOR_BGR2HSV.

So you need to change this line:

hsv_im = cv2.cvtColor(image, cv2.cv.CV_BGR2HSV)

to:

hsv_im = cv2.cvtColor(image, cv2.COLOR_BGR2HSV)
