I want to follow the tutorials of the face recognition with opencv. But in the tutorial source code example getMat() method is used, which is deprecated in opencv3.0. What can I use instead of getMat() now in opencv3.0?

This is the tutorial I am trying to follow - http://docs.opencv.org/3.0-beta/modul...

the interface has changed a bit, please have another look at the updated samples

it's all like: reco->getEigenValues() instead of reco->getMat("eigenvalues") and such.

also, do yourself a favour, and update both opencv and opencv_contrib repos (and rebuild) for consistancy

last, but not least, the beta docs are outdated, rather look here

Thank you for your answer. But the same error as before - class cv::face::FaceRecognizer has no member "getEigenValues". I installed opencv just a month ago and downloaded opencv_contrib repo weeks ago. Do I need to update both and rebuild again?

anyway, update, since you're on 3.0, get used to do a git pull on a regular basis (even if it's not for this issue only)
then, cv::face::FaceRecognizer does not have any of those methods, you want an instance of cv::face::BasicFaceRecognizer in this case.

Thank you very much. It worked.
