  int smallestSum = 9999999;
  int smallestSumIndex = -1;

      if (sums[i] < smallestSum)
      {

          smallestSumIndex = i;
      }
  }
  return circles[smallestSumIndex];
}

How can I determine the best parameters for houghcircles int cols,rows; cols=grimat2.cols();

thanks Mr.Türkmen(Teşekkür ederim Süleyman abi dediğini deneyeceğim.)
