estimateRigidTransform( ) in Opencv 3.0.0

edit

Does anyone know what library to include to use this function in opencv 3? I get the error: estimateRigidTransform() was not declared in this scope

My includes list:

#include "opencv2/core.hpp" #include "opencv2/core/utility.hpp" #include "opencv2/core/ocl.hpp" #include "opencv2/imgcodecs.hpp" #include "opencv2/highgui.hpp" #include "opencv2/features2d.hpp" #include "opencv2/calib3d.hpp" #include "opencv2/calib3d/calib3d_c.h" #include "opencv2/imgproc.hpp" #include "opencv2/xfeatures2d.hpp" #include "opencv2/imgproc/types_c.h" #include "opencv2/imgcodecs/imgcodecs_c.h" #include "opencv2/highgui/highgui_c.h"
