  * OpenBR \cite klontz2013open is a framework for investigating new modalities, improving existing algorithms, interfacing with commercial systems, measuring recognition performance, and deploying automated biometric systems.
  * The project is designed to facilitate rapid algorithm prototyping, and features a mature core framework, flexible plugin system, and support for open and closed source development.
  * Off-the-shelf algorithms are also available for specific modalities including \ref cpp_face_recognition, \ref cpp_age_estimation, and \ref cpp_gender_estimation.
