I2Head Database


We have created a public database combining ground truth data for head pose, gaze and simplified user face models of 12 individuals.
The hardware employed is a magnetic sensor (The Flock of Birds by Ascension Technologies) for 3D pose and a camera. The sensor is used to register the head pose with respect to the transmitter. The employed camera is a standard Logitech webcam with a resolution of 1280×720 pixels working at 30 fps.

The relative position between the transmitter and the camera has been carefully calibrated together with the positions of the fixations grid.

For each user, 8 sessions are recorded under controlled movements in static and free head movements’ scenarios. Point grids containing 17 and 65 fixations are recorded. For each fixation point the best 10 frames are selected providing an image and the head pose for each one of the samples. In addition a simplified head model for each user is provided.

Sample images taken from the database:
