How to find a spot inside circle Hi I am trying to process image1 so that I can find the spot as shown in image2 image1

thanks I figured it out

Hi in the below image how do you find and mark all the circles and identify the defect, my vs is vs2010 and opencv 2.4.10

this is my code so far, but it doesnt detect anything:

static void findCircles2(const Mat& image)
{
    vector<Vec3f> circles;
    int thresh1 = 5;
    Mat pyr, timg, gray0(image.size(), CV_8U), gray;
    pyrDown(image, pyr, Size(image.cols/2, image.rows/2));
    pyrUp(pyr, timg, image.size());
    for( int c = 0; c < 3; c++ )
    {
        int ch[] = {c, 0};
        mixChannels(&timg, 1, &gray0, 1, ch, 1);
        Canny(gray0, gray, 0, thresh1, 5);
        //dilate(gray, gray, Mat(), Point(-1,-1));
        gray = gray0 >= (1)*255/N;
        gray = gray0 >= (2)*255/N;
        gray = gray0 >= (6)*255/N;
        namedWindow( "Hough Circle Transform Demo 1", CV_WINDOW_AUTOSIZE );
        imshow( "Hough Circle Transform Demo 1", gray );
        waitKey(0);

        HoughCircles( gray, circles, CV_HOUGH_GRADIENT, 1, gray.rows/8, 200, 100, 0, 0 );
        cout<<"size of circles: "<<circles.size()<<endl;
        for( size_t i = 0; i < circles.size(); i++ )
        {
            Point center(cvRound(circles[i][0]), cvRound(circles[i][1]));
            int radius = cvRound(circles[i][2]);
            circle( gray, center, 3, Scalar(0,255,0), -1, 8, 0 );
            circle( gray, center, radius, Scalar(0,0,255), 3, 8, 0 );
        }

  /// Show your results
        namedWindow( "Hough Circle Transform Demo 2", CV_WINDOW_AUTOSIZE );
        imshow( "Hough Circle Transform Demo 2", gray );

         waitKey(0);

    }
}

how did you setup the floodfill command? thanks by the way

@sjhalayka sorry you had to resort to foul language, but thank you for pointing out that I hadn't said thank you. someti

thanks guys for your help, do you have any tuts on how to build binaries for vs2010
