Arrange from one end point to another?

Hello Santhosh! Here is a Sample Implementation to find the Edge points of a Contour! Hope this helps!

#include <opencv2\opencv.hpp>
#include "opencv2\opencv_modules.hpp"

using namespace cv;
using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{

    Mat mSrc= imread("D:\\Conti\\Image Samples\\forum\\Test.png",0);

    if(mSrc.empty())
    {
        cout<< "Invalid Input Image!";
        return 0;
    }

    Mat mSrc_Binary,mSrc_Contours,mEndPoints,mResult;

    //Creating a Binary Image
    threshold(mSrc,mSrc_Binary,1,255,THRESH_BINARY);

    //Make sure it is one Pixel width .i.e to replicate a contour Points
    thinning(mSrc_Binary,mSrc_Contours);


    Mat_<int> Kernal(3,3);
    Kernal <<   1, 1, 1,
                1,10, 1,
                1, 1, 1;

    //Multiply the Binary Image with the above Kernal

    */
    filter2D(mSrc_Contours,mEndPoints,CV_8UC1,Kernal);

    //We are interested in the pixels whicn are equal to 11
    inRange(mEndPoints,11,11,mEndPoints);

    //Just adding some Visualization!!
    cvtColor(mSrc_Binary,mResult,COLOR_GRAY2BGR);
    dilate(mEndPoints, mEndPoints, Mat(), Point(-1, -1), 2, 1, 1);//Make it Visible
    mResult.setTo(Scalar(0,0,255),mEndPoints);

    imshow("mResult",mResult);

    waitKey();
    return 0;
