How to convert colored image to HLS using Java OpenCV library?
You can convert HLS image to RGB (colored) image by passing Imgproc.COLOR_RGB2HLS as the 3rd parameter to the cvtColor() method.
Example
import org.opencv.core.Core;
import org.opencv.core.Mat;
import org.opencv.imgcodecs.Imgcodecs;
import org.opencv.imgproc.Imgproc;
public class HSL2RGB {
public static void main(String args[]) throws Exception {
System.loadLibrary( Core.NATIVE_LIBRARY_NAME );
Mat src = Imgcodecs.imread("D:\\images\\car3.jpg");
Mat dst = new Mat();
Imgproc.cvtColor(src, dst, Imgproc.COLOR_RGB2HLS);
Imgcodecs imageCodecs = new Imgcodecs();
imageCodecs.imwrite("D:\\images\\hslImage.jpg", dst);
System.out.println("Image Saved");
}
}Input
