Hi @zhuruixiang @tatagoswami , sorry for my long delayed feedback to you. Unfortunately part of the documentation is not up to date, there's no more bgs_demo.vcxproj on the main project. If you follow this step: https://github.com/andrewssobral/bgslibrary/wiki/Installation-instructions---Windows#how-to-compile-on-windows-10--msvs2019--opencv-347 You should see the bgslibrary.sln file to build the main project. If you want to compile the bgslibrary examples (bgs_demo, bgs_demo2, etc), you need to go inside the examples/build and do:

cmake -DOpenCV_DIR=%OpenCV_DIR% -G "Visual Studio 16 2019" ..

and you see the bgslibrary-examples.sln (see screenshot below)

For info, I just released a new version of the BGSLibrary, now v3.1.0. I tested it on Windows, Mac and Linux, both compiling the C++ library on OpenCV 3.4.7, 3.4.16 and 4.6.0. I also tested its respective Python wrapper and GT user interface.
