I am tring to use opencv and java for face detection, and in that pursit i found this "JNI2OPENCV" file....but i am confused on how to make it work, can anyone help me?

http://img519.imageshack.us/img519/4803/askaj.jpg

and the following is the FaceDetection.java

`class JNIOpenCV { static { System.loadLibrary("JNI2OpenCV"); } public native int[] detectFace(int minFaceWidth, int minFaceHeight, String cascade, String filename); }

public class FaceDetection { private JNIOpenCV myJNIOpenCV; private FaceDetection myFaceDetection;

public FaceDetection() { myJNIOpenCV = new JNIOpenCV(); String filename = "lena.jpg"; String cascade = "haarcascade_frontalface_alt.xml";

int[] detectedFaces = myJNIOpenCV.detectFace(40, 40, cascade, filename);
int numFaces = detectedFaces.length / 4;

 System.out.println("numFaces = " + numFaces);
 for (int i = 0; i < numFaces; i++) {
  System.out.println("Face " + i + ": " + detectedFaces[4 * i + 0] + " " + detectedFaces[4 * i + 1] + " " + detectedFaces[4 * i + 2] + " " + detectedFaces[4 * i + 3]);
 }

}

public static void main(String args[]) {
    FaceDetection myFaceDetection = new FaceDetection();   
}

}`

CAn anyone tell me how can i make this work on Netbeans?? I tried Google but help on this particular topic is very meger.

I have added the whole folder as Llibrary in netbeans project and whe i try to run the file i get the followig wrroes.

Exception in thread "main" java.lang.UnsatisfiedLinkError: FaceDetection.JNIOpenCV.detectFace(IILjava/lang/String;Ljava/lang/String;)[I at FaceDetection.JNIOpenCV.detectFace(Native Method) at FaceDetection.FaceDetection.<init>(FaceDetection.java:19) at FaceDetection.FaceDetection.main(FaceDetection.java:29) Java Result: 1 BUILD SUCCESSFUL (total time: 2 seconds)

CAn anyone tell me the exact way to work with this? like what all i have to do?
