HomeJavajavaTutorialHow to convert HSV to color image using Java OpenCV library?

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");
   }
}

Enter
