replace cv::String Str = imagepath; for std::string Str = imagepath;

thanks for your reply, i replace cv::String Str = imagepath; for std::string Str = imagepath in the line 221 and line 248 of main.cpp, it seems to encounter anothor problem in line 248 "std::string &Str = NameFaces[i];" with error "cannot initialize a reference of type "std::__cxx11::string &" with a value of type "cv::String" (non-const qualified)", how can i address it, thank you.

Dear @laminggg,

cv::String is linked to std::string. They are almost identical. Somehow your OpenCV installation doesn't support all the std::string calls. Best to use not cv::String but std::string. This way you know for sure everything works well. I have updated the code. Please replace main.cpp with the new version found in this repo.
