Hi,

I am trying to recompile OpenCV2. I have installed FFMPEG in /usr/local. I am more familiar with the ./configure scripts than with cmake. Do you know how to specify FFMPEG's prefix with cmake?

thanks!

I am trying to set the grouping settings in the hog.detectMultiScale method from the OpenCV2 library (version 2.4.9).

What happens is that the group_threshold and groupThreshold parameters are both not recognized in the python binding:

TypeError: 'group_threshold' is an invalid keyword argument for this function

and

TypeError: 'groupThreshold' is an invalid keyword argument for this function

How can I fix this? Is there a way to set this parameter?
