API #	TITLE	LINK
1	Face Recognition	Stephen here from Lambda Labs. For sample code and a graphical demo, check out http://api.lambdal.com/docs. Our API provides face recognition, facial detection, eye position, nose position, mouth position, and gender classification. If you have any questions ask! Just send an email to s@lambdal.com. Happy Hacking! -Stephen
2	Face (Detection)	A computer vision api for facial recognition and facial detection that is a perfect face.com replacement. We currently have a free api for face detection.
3	Animetrics Face Recognition	The Animetrics Face Recognition API can be used to detect human faces in pictures. Information on facial features or landmarks is returned as coordinates on the image.. Animetrics Face Recognition will also detect and return the orientation, or pose of faces along 3 axes.
4	Skybiometry Face Detection and Recognition	An easy to use Face Detection and Recognition API. You must have an application created in your account at SkyBiometry to use it (sign up at if you don’t have account yet).
5	Face++	Face++ uses the cutting-edge technology of computer vision and data mining to provide 3 core vision services (Detection, Recognition and Analysis). Our API provides the detection and analysis of Landmark (23points), Landmark (81 points), Attributes: Age,Gender, Glasses, Race, etc.
6	FaceMark	FaceMark is a powerful API for facial feature detection. It finds 68 points for a frontal face and 35 for a profile one. FaceMark detects landmarks for faces on the image specified by URL or uploaded as a file and produces JSON output containing a vector of facial landmarks and orientation for each face found.
7	EmoVu by Eyeris	Artificially Intelligent emotion recognition software that allows cameras to look back and read people’s facial micro-expressions, gender and age group in real time as they watch videos on their computers or mobile devices.
8	Face and scene recognition by Rekognition.com	Face.com alternative! Our fast, robust and scalable rekognition engine can do facial detection, crawling, recognition, scene understanding! It can be automatically trained using images and tags on Facebook!
9	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.
10	Betaface API	face detection and recognition
11	EyeFace	Enables face detection, landmark estimation and age / gender recognition in images.
12	Kairos	2D to 3D face detection and facial recognition API.
