First of all, don't mix C with C++. Include (and of course link against it) <opencv2/core/core.hpp>
(guess you do that already since the compiler suggest already using cv::-prefix) and use cv::putText()
. putText() is declared in the namespace cv
, so either write "using namespace cv
" above your class, or write the namespaces like cv:: and std:: explicitly to each command (I prefer the latter one so I always know where each command stems from).
