The cvtColor() method of the Imgproc class can convert the color of the image from one to another. This method accepts three parameters:

#src − Matrix object representing the source image.
dst − Matrix object representing the target image.
#code − An integer value representing the color of the target image.

To convert an HSV image to RGB, you need to pass Imgproc.COLOR_HSV2RGB as the third parameter to the method.

Example

import org.opencv.core.Core;
import org.opencv.core.Mat;
import org.opencv.imgcodecs.Imgcodecs;
import org.opencv.imgproc.Imgproc;
public class HSV2RGB {
   public static void main(String args[]) throws Exception {
      //Loading the OpenCV core library
      System.loadLibrary( Core.NATIVE_LIBRARY_NAME );
      //Reading the image
      Mat src = Imgcodecs.imread("D:\images\hsvimage.jpg");
      //Creating the empty destination matrix
      Mat dst = new Mat();
      //Converting the image to gray scale
      Imgproc.cvtColor(src, dst, Imgproc.COLOR_HSV2RGB);
      //Instantiating the Imagecodecs class
      Imgcodecs imageCodecs = new Imgcodecs();
      //Writing the image
      imageCodecs.imwrite("D:\images\hsv2rgb.jpg", dst);
      System.out.println("Image Saved");
   }
}
