I've been googling around all day trying to see if I can actually use these functions. Following this tutorial http://opencv-python-tutroals.readthedocs.org/en/latest/py_tutorials/py_feature2d/py_matcher/py_matcher.html I get a bunch of matches back, but I can't visualise them as it says no module named drawMatchesKnn.
When I check help (cv2) there is indeed no module named drawMatches. I installed opencv with Homebrew. Is there anything I can do about this?
If I can't use those functions, is there any documentation on how I can manipulate the match objects that are returned?
