Description

I have had significant trouble with the cv2 python bindings for feature extraction. I keep getting <unknown> is not a numpy array when I try to use the surf/star feature extractors. This may simply be for lack of working example code. Could you please verify that these methods work and perhaps post working examples? My problems are summarized here:

I have tried both the release and the current version in the SVN repo. I am OSX but I believe these errors are also present on Linux and Windows. If you want to point me in the right direction and lend some assistance I am more than willing to help fix these bindings in the source repository.

in the sample code you are trying to pass Python-wrapped iplimage to cv2. function. It will not work. Forget iplimage and use numpy arrays, as it's suggested in reply on stackoverflow.

Though, we still need samples for the functionality, so I leave this ticket open, but lower its priority.
