BufferedImage to JavaFX image

normally the best choice is Image image = SwingFXUtils.toFXImage(capture, null); in java9 or bigger.... but in matter of performance in javafx, also in devices with low performance, you can use this technique that will do the magic, tested in java8

private static Image convertToFxImage(BufferedImage image) {
    WritableImage wr = null;
    if (image != null) {
        wr = new WritableImage(image.getWidth(), image.getHeight());
        PixelWriter pw = wr.getPixelWriter();
        for (int x = 0; x < image.getWidth(); x++) {
            for (int y = 0; y < image.getHeight(); y++) {
                pw.setArgb(x, y, image.getRGB(x, y));
            }
        }
    }

    return new ImageView(wr).getImage();
}

You can use

Image image = SwingFXUtils.toFXImage(capture, null);
