--- Comment #20 from Gilles Caulier <caulier.gilles at gmail.com> ---
m_histograms dysfunction is certainly due to  haar cascade files from OpenCV
not loaded. But in this case, libkexiv2 must generate a warning in the console.

Also, take a care that harr cascade XML files from openCV 3 can be different
than OpenCV 2, and placed at a different place (OpenCV is a big puzzle).
Perhaps the path to parse from system to find haar cascade files must be patch
to support OpenCV 3.

Note: haar cascades files included in libkface as well are for Windows only, as
under windows, OpenCV 2 do not install these files...
