Video Stabilization - using estimateGlobalMotionLeastSquares opencv 2.4.7 - c

Question

I am a newbie about Video Stabilization field. Now I am researching about it.
I'm coding a small video stabilization demo. But I am stuck in some problems
I use the function "estimateGlobalMotionLeastSquares" in OpenCV to estimate global motion
But it doesn't work
Here is my code:
CvPoint2D32f p0, p1;
vector<Point2f,allocator<Point2f>> ax, by;
ax.push_back(Point2f(2,2));
by.push_back(Point2f(3,2));
Mat t = estimateGlobalMotionLeastSquares(ax,by,AFFINE,0);
For example: I create 2 variables p0,p1 as parameter for the function "
estimateGlobalMotionLeastSquares" and I want to estimate global motion "t".
But when I complied, the error is as:
1>VS_OpenCVDlg.obj : error LNK2001: unresolved external symbol "class cv::Mat __cdecl cv::videostab::estimateGlobalMotionLeastSquares(class std::vector,class std::allocator > > const &,class std::vector,class std::allocator > > const &,int,float *)" (?estimateGlobalMotionLeastSquares#videostab#cv##YA?AVMat#2#ABV?$vector#V?$Point_#M#cv##V?$allocator#V?$Point_#M#cv###std###std##0HPAM#Z)
1>F:\Research\Workspace\VS_OpenCV\Debug\VS_OpenCV.exe : fatal error LNK1120: 1 unresolved externals
Please help me to fix this!!!
Can you give me some examples about that function it?

Answer 1

Try to include the proper file :
#include "opencv2/videostab/videostab.hpp"
And change your code to :
CvPoint2D32f p0, p1;
vector<Point2f,allocator<Point2f>> ax, by;
ax.push_back(Point2f(2,2));
ax.push_back(Point2f(2,3));
ax.push_back(Point2f(2,4));
by.push_back(Point2f(3,2));
by.push_back(Point2f(3,3));
by.push_back(Point2f(3,4));
Mat t = videostab::estimateGlobalMotionLeastSquares(ax,by,3,0);
