Today I read a paper titled “Three-Dimensional Face Orientation and Gaze Detection from a Single Image”
The abstract is:
Gaze detection and head orientation are an important part of many advanced human-machine interaction applications.
Many systems have been proposed for gaze detection.
Typically, they require some form of user cooperation and calibration.
Additionally, they may require multiple cameras and/or restricted head positions.
We present a new approach for inference of both face orientation and gaze direction from a single image with no restrictions on the head position.
Our algorithm is based on a face and eye model, deduced from anthropometric data.
This approach allows us to use a single camera and requires no cooperation from the user.
Using a single image avoids the complexities associated with of a multi-camera system.
Evaluation tests show that our system is accurate, fast and can be used in a variety of applications, including ones where the user is unaware of the system.
