setLabelsInfo not existing in opencv3?

edit

That's awesome, thanks so much berak!

Hmm i just noticed the new setLabelInfo has 2 arguments. The old one just had one: std::map<int, string="">& labelsInfo

model->setLabelsInfo(labelsInfo);

How should i change the above line now that it expects 2 arguments?

hmm, i can only guess, but i think, you're supposed to put that function somewhere, where you read your images, and add a name & label at a time there.

That's exactly it. In main() it's defined as: std::map<int,string> labelsInfo; Ptr<basicfacerecognizer> model = createFisherFaceRecognizer(0,400.0); //Ptr<facerecognizer> model = createEigenFaceRecognizer(10,6000.0); //Ptr<facerecognizer> model = createLBPHFaceRecognizer(); model->setLabelInfo(labelsInfo);

and in read_csv : static void read_csv(const string& filename, vector<mat>& images, vector<int>& labels, std::map<int, string="">& labelsInfo, char separator = ';') {

It seems the type has changed from std::map <int,string>&labelsInfo to const string& strInfo and to 1 argument.

I'm not sure how to change that so i'm at a bit of a loss. My apologies for not being that proficient with c++ code, i'd appreciate the help.

Is there no conversion guide for opencv2 to 3? I'm

well, none of this is your fault, actually ;)

this whole interface has become a terrible kludge over time, you know, too many cooks ..

for now, i'd suggest, that you doit like here , that is - fill the map, while you're reading the csv, and later copy things int your model

once, you got it running, and got some feel for what's happenning, -- take the AXE, break it apart, STEAL the good parts, and build something better , really ;)

Gotcha, that looks like it should work. Thanks again!
