    public class Facemark
    extends Algorithm
    Abstract base class for all facemark models To utilize this API in your program, please take a look at the REF: tutorial_table_of_content_facemark ### Description Facemark is a base class which provides universal access to any specific facemark algorithm. Therefore, the users should declare a desired algorithm before they can use it in their application. Here is an example on how to declare a facemark algorithm: // Using Facemark in your code: Ptr<Facemark> facemark = createFacemarkLBF(); The typical pipeline for facemark detection is as follows:
    • Load the trained model using Facemark::loadModel.
    • Perform the fitting on an image via Facemark::fit.

      • Facemark

        protected Facemark​(long addr)
    • Method Detail

      • __fromPtr__

        public static Facemark __fromPtr__​(long addr)
      • loadModel

        public void loadModel​(String model)
        A function to load the trained model before the fitting process.
        Parameters:
        model - A string represent the filename of a trained model. <B>Example of usage</B> facemark->loadModel("../data/lbf.model");
      • fit

        public boolean fit​(Mat image,
                           MatOfRect faces,
                           List<MatOfPoint2f> landmarks)
        Detect facial landmarks from an image.
        Parameters:
        image - Input image.
        faces - Output of the function which represent region of interest of the detected faces. Each face is stored in cv::Rect container.
        landmarks - The detected landmark points for each faces. <B>Example of usage</B> Mat image = imread("image.jpg"); std::vector<Rect> faces; std::vector<std::vector<Point2f> > landmarks; facemark->fit(image, faces, landmarks);
        Returns:
        automatically generated
