SURF in opencv3 [closed]

edit

Hi. Thanks for the answer. I'm done with configuring the opencv_contrib modules. Now, i'm using the surf code and it's giving me the error on this line: Ptr<surf> detector = SURF::create(minHessian);

it says: Severity Code Description Project File Suppression State Line Error LNK2019 unresolved external symbol "public: static struct cv::Ptr<class cv::xfeatures2d::surf=""> __cdecl cv::xfeatures2d::SURF::create(double,int,int,bool,bool)" (?create@SURF@xfeatures2d@cv@@SA?AU?$Ptr@VSURF@xfeatures2d@cv@@@3@NHH_N0@Z) referenced in function "public: __thiscall SURFDetector::SURFDetector(double)" (??0SURFDetector@@QAE@N@Z) OpencvSURF C:\Users\Hassam\documents\visual studio 2015\Projects\OpencvSURF\OpencvSURF\Source.obj 1

Can you tell me the solution?

In link option you must have opencv_xfeatures2d310.lib

Hey, thank you very much. I downloaded the opencv_xfeatures2d310.lib and paste it in the lib folder and linked it to VS2015 by going in additional dependencies of DEBUG and RELEASE mode. The build was successful, but an error occurred saying : 'The program can't start because opencv_xfeatures2d310.dll is missing from your computer. Try reinstalling the program to fix this problem' Can you help? please?

You should installed opencv in open solution and add opencv path in system environement. If you want to solve faster your problem copy opencv_xfeatures2d310.dll where is your exe it's not good way because you will have to copy this dll for every new project...

Thanks for replying. I've used cmake software to work with the extra modules. I found that way on youtube. Anyways, sir I've copied the opencv_xfeatures2d310 file to the folder where my visual studio project exe is located. It is still giving me the error. Nothing changes. Can you help?

I've fixed the issue. Thanks for your help Berger. :)

How have you fixed the issue ?
