I'm trying to build a detector for face detection in images. I use the OpenCV library, version 2.4.11.
Now my source code looks like following :
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.objdetect.CascadeClassifier;
public class DetectFaces {
public static void main(String[] args) {
System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
System.out.println("\nRunning FaceDetector");
CascadeClassifier faceDetector = new CascadeClassifier(FaceDetector.class.getResource("haarcascade_frontalface_alt.xml").getPath());
Mat image = Highgui
.imread(FaceDetector.class.getResource("pic.JPG").getPath());
MatOfRect faceDetections = new MatOfRect();
faceDetector.detectMultiScale(image, faceDetections);
// System.out.println(String.format("Detected %s faces", faceDetections.toArray().length));
for (Rect rect : faceDetections.toArray()) {
Core.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));
Highgui.imwrite(filename, image);
}
}
Now I get an FaceDetector cannot be resolved to a type
exception every time FaceDetector.class
is called.
While working on this implementation I am following the tutorial
Any suggestions are welcome. Thank You
