Detecting a Gazing Region by Visual Direction and Stereo Cameras
We develop a wearable vision system that consists of a user’s visual direction sensor and stereo cameras. First, we establish a method for calibrating the system so that it can ...

Cyclorotation Models for Eyes and Cameras
The human visual system obeys Listing's law, which means that the cyclorotation of the eye (around the line of sight) can be predicted from the direction of the fixation point...

On Constant Focal Length Self-Calibration From Multiple Views
We investigate the problem of finding the metric structure of a general 3D scene viewed by a moving camera with square pixels and constant unknown focal length. While the problem ...
