Is cv2.cv missing in OpenCV 3.0?

Question

I've just installed OpenCV 3 on Win7 for using with Python 2.7. I've copied cv2.pyd to /DLLs.

Unfortunately many examples I've tried, don't work, because cv2.cv seems to be missing in OpenCV3

Is there a replacement for it? Is there a table of new constant-names used to be declared in cv2.cv?

Many thanks!

yes, the deprecated cv2.cv was removed in opencv3.0

something similar to:

import cv2

help(cv2)

will give you a (looong) list of the api's content.

To get old examples to work, you need to create/edit a file cv.py in site-packages with the following single line of text:

import cv2 as cv

OK I tried this briefly - had some success but then started writing fresh code for cv2 - was easier than trying to get old code that imported cv2.cv working. – Ninga Aug 19 '16 at 01:04

Its not there in 3. Only cv2 is present.And also instead of functions being cv.something its now cv2.You can import cv2 and check the changes.
