I found out the recent master is not usable if one want to use those functions with python located in nonfree/contrib. Because most of those functions are blacklisted since 11/08/2014. Hope they will come back soon.

in modules/python/common.cmake

@berak Thanks!

2014-08-20 06:43:58 -0500 asked a question -DBUILD_opencv_nonfree:BOOL="1" has no effect in 3.0?

I cannot build the nonfree modules in opencv 3.0. The -DBUILD_opencv_nonfree:BOOL="1" has no effect at all. How can I build them?

Are they expected, or there is some configuration in my system to cause those errors?

Can anyone confirm this? In 2.4.9 lots of functions are missing for example: cv2.drawMatches
