How to convert HSV to BGR image using Java OpenCV library?
The cvtColor() method of the Imgproc class changes/converts the color of the image from one to another. This method accepts three parameters −
src − A Matrix object representing source.
dst − A Matrix object representing the destination.
code − An integer value representing the color of the destination image.
To convert an HSV image to BGR you need to pass Imgproc.COLOR_HSV2BGR as the 3rd parameter to the cvtColor() method.
Example
public class HSV2RGB {
public static void main(String args[]) throws Exception {
System.loadLibrary( Core.NATIVE_LIBRARY_NAME );
Mat src = Imgcodecs.imread("D:\images\hsvimage2.jpg");
Mat dst = new Mat();
Imgproc.cvtColor(src, dst, Imgproc.COLOR_HSV2BGR);
Imgcodecs imageCodecs = new Imgcodecs();
imageCodecs.imwrite("D:\images\hsv2bgr.jpg", dst);
System.out.println("Image Saved");
}
}Input
