| FacemarkTrain | Abstract base class for trainable facemark models
 To utilize this API in your program, please take a look at the REF: tutorial_table_of_content_facemark
 ### Description
 The AAM and LBF facemark models in OpenCV are derived from the abstract base class FacemarkTrain, which
 provides a unified access to those facemark algorithms in OpenCV. | 
| FaceRecognizer | Abstract base class for all face recognition models
 All face recognition models in OpenCV are derived from the abstract base class FaceRecognizer, which
 provides a unified access to all face recongition algorithms in OpenCV. |
