as coordinates on the image.. Animetrics Face Recognition will also
detect and return the orientation, or "pose" of faces along 3 axes.

orientation for each face found.

automatically trained using images and tags on Facebook!

FaceRect
- FaceRect is a powerful and free API for face detection. It finds
faces (both frontal and profile) on the image specified by URL or
uploaded as a file and is able to find multiple faces on a single photo,
producing JSON output with a bounding box for each face found.

OpenCV Face Recognizer - OpenCV (Open Source Computer Vision Library: OpenCV | OpenCV) is an open-source BSD-licensed library that includes several hundreds of computer vision algorithms.

Libface
- Libface is a library aimed at bringing face recognition technology to
the open source community. It is written in C++ and maintained on Sourceforge. The library uses OpenCV 2.0
and aims to be a middleware for developers that don’t have to include
any OpenCV code in order to use face recognition and face detection
detection.

Automatic naming of characters in video -
The objective of this work is to label television or movie footage with
the names of the people present in each frame of the video.

analyzing facial expressions, providing users with an objective
assessment of a person’s emotion.

Affdex
- Affdex reads emotional states such as liking and attention from
facial expressions using a webcam... to give marketers faster, more
accurate insight into consumer response to brands and media.

Faceware - Analyzer takes in a video of an actor’s facial performance and produces an .IMPD file for use in Retargeter™.
It accomplishes this through the combination of simple user input on
the front end, and complex computer vision algorithms on the back end.
