I have tried using:-
cv::Ptr<face::facerecognizer> model, mouthModel;
error: ‘face’ cannot appear in a constant-expression
cv::Ptr<face::facerecognizer> model, mouthModel;
The same code compiles perfectly on my friends laptop,and the only difference i am able to understand is he have installed opencv in usr/local while i have the same in downloads folder.
Kindly help,because i have been stuck around this from couple of days. I have even installed extra folders from https://github.com/itseez/opencv_contrib, but no difference.
These are relevant parts of code,
I am trying to detect a mouth and face and then create a database of the same.
