Hi, yjxiong
After make -j , something was wrong.
dense_flow.h:9:27: fatal error: easylogging++.h: No such file or directory
compilation terminated.
make[2]: *** [CMakeFiles/denseflow.dir/src/dense_flow.cpp.o] Error 1
make[1]: *** [CMakeFiles/denseflow.dir/all] Error 2

The version of Opencv is 3.2.0 or 3.0.0. A lot of methods have been tried!

Can you give me some ideas!

Thank you very much!
