Question

我正在尝试在JavaCV中实现EigenFace Recognition并通过以下代码实现它： -

    public static void main(String[] args) {
    String trainingDir = "C:/Users/user/Documents/NetBeansProjects/Face/testimg";

    IplImage testImage = cvLoadImage("C:/Users/user/Desktop/aa.png");

    File root = new File(trainingDir);

    FilenameFilter pngFilter = new FilenameFilter() {
        public boolean accept(File dir, String name) {
            return name.toLowerCase().endsWith(".png");
        }
    };

    File[] imageFiles = root.listFiles(pngFilter);

    MatVector images = new MatVector(imageFiles.length);

    int[] labels = new int[imageFiles.length];

    int counter = 0;
    int label;

    IplImage img;
    IplImage grayImg = null;
    try {
        for (File image : imageFiles) {
            img = cvLoadImage(image.getAbsolutePath(), CV_BGR2GRAY);
            int yer = image.getName().indexOf(".");
            String isim = image.getName().substring(0, yer);

            label = Integer.parseInt(isim);

            images.put(counter, img);

            labels[counter] = label;

            counter++;
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    IplImage greyTestImage = IplImage.create(testImage.width(), testImage.height(), IPL_DEPTH_8U, 1);

   //FaceRecognizer faceRecognizer = createFisherFaceRecognizer();
    FaceRecognizer faceRecognizer = createEigenFaceRecognizer();
    //FaceRecognizer faceRecognizer = createLBPHFaceRecognizer()

    faceRecognizer.train(images, labels);

    cvCvtColor(testImage, greyTestImage, CV_BGR2GRAY);

    int predictedLabel = faceRecognizer.predict(greyTestImage);

    System.out.println("Predicted label: " + predictedLabel);
  }

但是每次我运行它都会给我一个错误

OpenCV错误：图像步骤错误（矩阵不连续，因此其行数无法更改）在cv :: Mat :: reshape，file ........ \ opencv \ modules \ core \ src \ matrix.cpp，第802行线程＆＃34; main＆＃34;中的例外情况java.lang.RuntimeException：........ \ opencv \ modules \ core \ src \ matrix.cpp：802：error：（ - 13）矩阵不连续，因此其行数无法更改在函数cv :: Mat :: reshape
中

我已经阅读了一些在图像大小不同且不是8的倍数时发生的情况，但是我拥有相同大小和灰度级的所有图像。我用于保存检测到的面部的代码是： - < / p>

    Mat image_roi = new Mat(frame,rect_Crop);
    Imgproc.cvtColor(image_roi, image_roi, Imgproc.COLOR_BGR2GRAY);
    Size sz = new Size(240,240);
    Imgproc.resize( image_roi, image_roi, sz );
    String filename = "testimg\\" +jTextField1.getText() + ".png";
    System.out.println(String.format("Writing %s", filename));
    Imgcodecs.imwrite(filename, image_roi);

它也给了我

java.lang.NumberFormatException：

我的文件不知道为什么..... ??? 请帮帮...... !!!!
