How to use FeatureDetector in OpenCV C++? -


i using vs 2008 opencv 2.1 installed per installation guide. featuredetector/surffeaturedetector listed classes in documentation, considered "syntax error : identifier 'surffeaturedetector"

this pretty entirety of code.

#include "cv.h" #include "highgui.h"  ptr<featuredetector> *detect = new surffeaturedetector();

i've tried bunch of random combinations work. how can initialize featuredetector?

i think have installation problem, try resinstalling here: sourceforge.net/projects/opencvlibrary/files/opencv-win/2.2

anther other option precompiler has __opencv_old_cv_h__ defined. try undefining before #include "cv.h"

when type #include "cv.h" automatically should include featurs2d. in fact cv.h includes following:

#include "opencv2/core/core_c.h" #include "opencv2/core/core.hpp" #include "opencv2/imgproc/imgproc_c.h" #include "opencv2/imgproc/imgproc.hpp" #include "opencv2/video/tracking.hpp" #include "opencv2/features2d/features2d.hpp" #include "opencv2/flann/flann.hpp" #include "opencv2/calib3d/calib3d.hpp" #include "opencv2/objdetect/objdetect.hpp" #include "opencv2/legacy/compat.hpp"
