java - 带有openCV的FaceRecognizer

我正在使用openCV 2.4.9 Java库，在实现某些FaceRecognizer时遇到一些问题。我知道在C ++中，类contrib.FaceRecognizer是Abastract，但是我不知道Java库是否也会发生这种情况（实际上Java文档太稀缺了！）。无论如何，这是我给班级打电话的尝试：

FaceRecognizer rec = new FaceRecognizer();
要么
FaceRecognizer rec = null;或
FaceRecognizer rec;

最后，我试图以这种方式调用Train和Predict方法：

public static void main(String[] args) {
    // TODO code application logic here
    System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
    FaceRecognizer rec = null;
    List<Mat> images;
    images = new ArrayList<Mat>();
    images.add(Highgui.imread("/home/adriano/Desktop/fotos/gabi/1.jpg"));
    images.add(Highgui.imread("/home/adriano/Desktop/fotos/gabi/2.jpg"));
    images.add(Highgui.imread("/home/adriano/Desktop/fotos/gabi/3.jpg"));
    images.add(Highgui.imread("/home/adriano/Desktop/fotos/estevao/1.jpg"));
    images.add(Highgui.imread("/home/adriano/Desktop/fotos/estevao/2.jpg"));
    images.add(Highgui.imread("/home/adriano/Desktop/fotos/estevao/3.jpg"));

    Mat labels = new Mat(1, 6, CvType.CV_8UC1, Scalar(0));
    // How can I add some values different from 0 to this Mat?


    rec.train(images, labels);


    // Predicts the label
    System.out.println(testando.predict(Highgui.imread("/home/adriano/Desktop/fotos/gabi/4.jpg"));


    }

最佳答案

使人脸识别器可以使用

FaceRecognizer rec=createLBPHFaceRecognizer();

要么

FaceRecognizer rec=createEigenFaceRecognizer();

要么

FaceRecognizer rec=createFisherFaceRecognizer();
