I am not able to add open cv blobs library with visual studio 2013, i need to calculate contourArea which needs blobs library ,how can i add those libraries.

 #include<opencv2/highgui/highgui.hpp>
#include<opencv/cv.h>
#includeopencv2/imgproc/imgproc.hpp

#include <opencv2\opencv.hpp>

#include<stdio.h>
#include<iostream>
using namespace std;`int main()
{
    // open the image   
    cv::Mat &image= cv::imread("cancer.jpg");
    vector<vector<Point> > contours;
    cv::Canny(image, // gray-level image
        contours, // output contours
        125, // low threshold
        350);


    or(unsigned int i=0;i<contours.size(),i++)
{
     cout << "# of contour points: " << contours[i].size() << endl ;

     for(unsigned int j=0;j<contours[i].size(),j++)
     {
         cout << "Point(x,y)=" << contours[i][j] << endl;
     }

     cout << " Area: " << contourArea(contours[i]) << endl;//its contourArea() is undefined
}

     cvWaitKey(0);
 }
