While I use haarcascade_upperbody.xml to detection in videocapture, I never get any error or problem but when I used haarcascade_fullbody.xml program couldn't detect anyone's body.. I am going to use finding human heigth...if you give some hints, solutions or advising another way for this problem...thanks for reading
here is my code :
package main;
import javax.swing.JOptionPane;
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.highgui.Highgui;
import org.opencv.highgui.VideoCapture;
import org.opencv.objdetect.CascadeClassifier;
public class ResimCek {
public void resimCek() throws InterruptedException{
System.loadLibrary("opencv_java244");
CascadeClassifier cascadeClassifier = new CascadeClassifier("haarcascade_fullbody.xml");
VideoCapture cap = new VideoCapture(0);
if(!cap.isOpened())
JOptionPane.showMessageDialog(null, "Cam can not found", "Error", JOptionPane.ERROR_MESSAGE);
Mat frame = new Mat();
cap.retrieve(frame);
Highgui.imwrite("cek.jpg", frame);
cap.release();
Mat resim = Highgui.imread("cek.jpg");
MatOfRect rect = new MatOfRect();
cascadeClassifier.detectMultiScale(resim, rect);
Scalar renk = new Scalar(255, 0, 0);
for(Rect dik : rect.toArray()){
Core.rectangle(resim, new Point(dik.x, dik.y), new Point(dik.x+ dik.width, dik.y+dik.height), renk);
}
System.out.println(rect.height());
Highgui.imwrite("dene.jpg", resim);
}
}
