I'm trying to use SiftFeatureDetector but i'm having undeclared identifier error. But i imported the libraries as follows. Any help is appreciated. ( i followed This article

imported libraries

#include <opencv2/features2d.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/core/core.hpp>
#include <opencv2/features2d/features2d.hpp>

I'm using opencv 2.4
