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
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
<ipython-input-2-15a6578c139c> in <module>()
----> 1 from cv2 import cv
ImportError: cannot import name cv
However, I have some legacy code of the form:
hsv_im = cv2.cvtColor(image, cv2.cv.CV_BGR2HSV)
When running this, I get the error:
In [7]: hsv_im = cv2.cvtColor(image, cv2.cv.CV_BGR2HSV)
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
<ipython-input-7-e784072551f2> in <module>()
----> 1 hsv_im = cv2.cvtColor(image, cv2.cv.CV_BGR2HSV)
AttributeError: 'module' object has no attribute 'cv'
What is the equivalent of this code in OpenCV3?
From OpenCV 2.X OpenCV 3.0 a few things changed.
Specifically:
cv2.cv
doesn't exists in OpenCV 3.0. Use simply cv2
.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)
