/**
 * @param num_components The number of components (read: Eigenfaces) kept for this Principal
 *     Component Analysis. As a hint: There's no rule how many components (read: Eigenfaces) should be
 *     kept for good reconstruction capabilities. It is based on your input data, so experiment with the
 *     number. Keeping 80 components should almost always be sufficient.
 * @param threshold The threshold applied in the prediction.
 *
 *     ### Notes:
 *
 *     -   Training and prediction must be done on grayscale images, use cvtColor to convert between the
 *         color spaces.
 *     -   **THE EIGENFACES METHOD MAKES THE ASSUMPTION, THAT THE TRAINING AND TEST IMAGES ARE OF EQUAL
 *         SIZE.** (caps-lock, because I got so many mails asking for this). You have to make sure your
 *         input data has the correct shape, else a meaningful exception is thrown. Use resize to resize
 *         the images.
 *     -   This model does not support updating.
 *
 *     ### Model internal data:
 *
 *     -   num_components see EigenFaceRecognizer::create.
 *     -   threshold see EigenFaceRecognizer::create.
 *     -   eigenvalues The eigenvalues for this Principal Component Analysis (ordered descending).
 *     -   eigenvectors The eigenvectors for this Principal Component Analysis (ordered by their
 *         eigenvalue).
 *     -   mean The sample mean calculated from the training data.
 *     -   projections The projections of the training data.
 *     -   labels The threshold applied in the prediction. If the distance to the nearest neighbor is
 *         larger than the threshold, this method returns -1.
