For Non-Photorealistic Rendering, the demo video had mentioned about GPU, which processed video in real-time. This video is from the reference paper. I would like to know if OpenCV had already implemented it on GPU or not? Thanks!

You're right, it works! Thanks a lot for your solution and sorry for such a simple question. BTW, thanks for editing my question which makes it look more clearly :-)

Okay,sorry for misunderstanding...

I tried to use the code form http://docs.opencv.org/3.1.0/d2/d0a/t...

I already compiled opencv_contrib with Cmake and added tracker.hpp into opencv2. After debugging, I got some errors as below:

Error   LNK2019 unresolved external symbol "public: bool __cdecl cv::Tracker::init(class cv::Mat const &,class cv::Rect_<double> const &)" (?init@Tracker@cv@@QEAA_NAEBVMat@2@AEBV?$Rect_@N@2@@Z) referenced in function main

Here is the link of LNK2019

I found some information from google that there might be some external symbols, but there was no useful solution to avoid it...I need some suggestions since I have no idea fixing these errors :-(

Thanks a lot!
