2014-02-05 08:25:40 -0600	commented answer	GPU accelerated cascade classifier training, is it in the pipeline? Anyone has tried this before? I think you're right - after looking at it some more, there is not much speed difference between training with CUDA on and off, at least as of today's master branch.

If you build OpenCV with CUDA flags with driver installed, opencv_traincascade will use CUDA: `$ otool -L bin/opencv_traincascade bin/opencv_traincascade: @rpath/libcudart.5.5.dylib (compatibility version 0.0.0, current version 5.5.28) ... @rpath/libcublas.5.5.dylib (compatibility version 0.0.0, current version 5.5.28) @rpath/libcufft.5.5.dylib (compatibility version 0.0.0, current version 5.5.28) ...`

I had the same problem and then followed instructions at http://juliensimon.blogspot.fr/2013/08/howto-compiling-ffmpeg-x264-mp3-aac.html to get rid of them.
