I am trying to connect Weka with Mysql database but its showing "jdbc driver not found" and i had already installed MYSQL driver, then also its showing the same error.

well thanks, i will post all snapshots of the output to get all people suggestions,of improving more, and will put the code on Github.

I am working on project to detect lungs cancer i had included algorithms for feature extraction like binarization,contours,contourArea,threshold,SIFT(to make more efficient ),Region Growing,Region of Interest(ROI),watershed . Which algorithms should i add more to make 97-98% efficiency of detection ? I want to detect cancer in its very 1 stage.

PS:-I am also using Data mining concepts like Decision tree to get probable data(other way to make more efficient project).

thanks matman its working, thanks people you all helped me alot!

@theodore i am using open cv 2.4.10 with visual studio 2013 is there any problem with that?

now its showing "identifier point is undefined",same showing for contourArea,now what do to @theodore?

@theodore thanks for helping i had set path all are working fine except contourArea()?

Its still showing contourArea(),"identifier not found" what you said i had included? There is some packages problems or libraries is missing ? I am using open cv 2.4.10 with visual studio 2013.

That i had done,its some other issues please check?

hey,Berak thanks for the reply i added the code above please check what exactly the problem is.

i had already included that header file still its showing "contourArea() is undefined" Is function contourArea() declaration is wrong? if yes, how we need to declare that?

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. EDIT:-I had used all the instructions given below my contourArea() is still showing undefined,please help?

    #include <opencv2/opencv.hpp>

    #include<stdio.h>
    #include<iostream>

    using namespace std;
    using namespace cv;

   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);

        for(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);
    }

Hello, How can i put blobs lib in visual studio 2013,i am not able to run codes having blobs with open cv and visual studio 2013,Please Help??

I am getting an error:-"contourArea is undefined" when i am using contourArea() to calculate the area of a particular object in my input image.I am using OpenCv with Visual Studio.How to remove this error?
