[Solved] Background MOG Substractor unreferenced - OpenCV 3.1.0

edit

Hi ,

I am here because i do not come up to use a MOG background substractor with OpendCV 3.1.0

I don't know if it is an include probleme or anything else.

I followed this official tutorial :http://docs.opencv.org/3.1.0/d1/dc5/tutorial_background_subtraction.html#gsc.tab=0

But when i try to create a MOG background substractor like this:

Ptr<BackgroundSubtractor> pMOG; //MOG Background subtractor
Ptr<BackgroundSubtractor> pMOG2; //MOG2 Background subtractor
...
//create Background Subtractor objects
pMOG = createBackgroundSubtractorMOG(); //MOG approach
pMOG2 = createBackgroundSubtractorMOG2(); //MOG2 approach

i get the error: cv has no member named "createBackgroundSubtractorMOG"

Can someone help me?

Edit: I write my own code, i can use the MOG2 but i can't find the simple MOG background substractor.

Solution: Thanks to berak: MOG was moved to opencv_contrib

Importing Contrib to OpenCV: Thanks to the Readme.md in github, i saw that the best way to improt contrib is to rebuild openCV using special option on CMake.

As a temporrary solution i copied the files in an external folder and i included them in my project.

As berak pointed out, the background substractor is in a new namespace, cv::bgsegm::createBackgroundSubtractorMOG(..)
