Subject: Segmentation.hpp: adapt the code to OpenCV 3
X-Git-Url: https://git.ao2.it/experiments/opencv_trail_effect.git/commitdiff_plain/79d57b3dedad2f0ae675bacc63470a5af1a176e6?hp=79d57b3dedad2f0ae675bacc63470a5af1a176e6

Segmentation.hpp: adapt the code to OpenCV 3

In OpenCV 3 the public cv::BackgroundSubtractorMOG2() is now abstract so
we cannot inherit directly from it.

The concrete class would be BackgroundSubtractorMOG2Imp from
modules/video/src/bgfg_gaussmix2.cpp but it is private so we cannot
inherit from it either.

Use the factory method as documented to get a cv::BackgroundSubtractor
instance of the desired type and use is as a property in the
MOG2Segmentation class.
