我正在特灵使用opencv和java来进行人脸检测，在这个过程中我发现了这个“JNI2OPENCV”文件....但是我对如何使它工作感到困惑，有人能帮助我吗？

下面是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();   
    }
}

有没有人能告诉我，我怎么才能让这个工作在Netbeans上？？我试过谷歌，但在这个特定的主题上的帮助是非常meger。
我已经在netbeans项目中添加了整个文件夹作为Llibrary，当我试图运行该文件时，我得到了以下错误。
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)
有人能告诉我具体的处理方法吗？比如我要做的是什么？
