DigiFace is a software project which I am planning to put on proper wheels so it can start rolling.

Some of current functionalities:
- face detection
- facial feature detection - eyes, mouth (3 points)
- facial feature tracking - eyes, mouth (3 points)

Some of planned functionalities:
- full feature detections - adding eyebrows, nose, ears, more detection points
- pose and angle evaluation
- face recognition
- 3D face modeling based on face samples

Main site for the project:

Some video demos:
Part 1
Face and facial feature detection and then tracking:

Part 2
Face and facial feature detection and then tracking:

Part 3
Face and facial feature detection and then tracking with adaptive zoom, i.e. camera has no optical zoom nor a pan/tilt mechanism, but it simulates it all these using digital zoom and sub-framing, so the face is always in focus:

More to come…
