[OpenCV Java] FaceDetection

kali ini kita mencoba  bagaimana menggunakan library openCV di java untuk aplikasi Face Detection:

Source code:

import org.opencv.core.Core;
import org.opencv.core.Mat;
import org.opencv.core.MatOfRect;
import org.opencv.core.Point;
import org.opencv.core.Rect;
import org.opencv.core.Scalar;
import org.opencv.imgcodecs.Imgcodecs;
import org.opencv.imgproc.Imgproc;
import org.opencv.objdetect.CascadeClassifier;
public class FaceDetector {
    public static void main(String[] args) {
        System.out.println("\nRunning FaceDetector");
        CascadeClassifier faceDetector = new CascadeClassifier("direktori/lbpcascade_frontalface.xml"); //isi direktori dimana lbpcascade_frontalface.xml berada
        Mat image = Imgcodecs.imread("direktori/xxxx.png");//isi direktori dimana gambar berada
        MatOfRect faceDetections = new MatOfRect();
        faceDetector.detectMultiScale(image, faceDetections);
        System.out.println(String.format("Detected %s faces", faceDetections.toArray().length));
        for (Rect rect : faceDetections.toArray()) {
        	Imgproc.rectangle(image, new Point(rect.x, rect.y), new Point(rect.x + rect.width, rect.y + rect.height),
                    new Scalar(0, 255, 0));
        String filename = "ouput.png";
        System.out.println(String.format("Writing %s", filename));
        Imgcodecs.imwrite(filename, image);
