Java OpenCVライブラリを使用して画像の鮮明度を変更するにはどうすればよいですか？

例

import org.opencv.core.Core;
import org.opencv.core.Mat;
import org.opencv.core.Size;
import org.opencv.imgcodecs.Imgcodecs;
import org.opencv.imgproc.Imgproc;
public class AlteringSharpness {
   public static void main (String[] args) {
      //Loading the OpenCV core library
      System.loadLibrary( Core.NATIVE_LIBRARY_NAME );
      //Reading the Image from the file
      String file ="D:\\Image\\lamma1.jpg";
      Mat src = Imgcodecs.imread(file, Imgcodecs.IMREAD_COLOR);
      //Creating an empty matrix
      Mat dest = new Mat(src.rows(), src.cols(), src.type());
      Imgproc.GaussianBlur(src, dest, new Size(0,0), 10);
      Core.addWeighted(src, 1.5, dest, -0.5, 0, dest);
      // Writing the image
      Imgcodecs.imwrite("D:\\Image\\altering_sharpness_100.jpg", dest);
   }
}
