Dense Shape Reconstruction of a Moving Object under Arbitrary, Unknown Lighting
We present a method for shape reconstruction from several images of a moving object. The reconstruction is dense (up to image resolution). The method assumes that the motion is kn...

Active Lighting for Object Brightness Control
We present an active lighting method that can control brightness of multiple objects in a scene to any values on video images. Our approach does not modify pixel values like retou...

Combining Kalman Filtering and Mean Shift for Real Time Eye Tracking under Active IR Illumination
Most eye trackers based on active IR illumination require distinctive bright pupil effect to work well. However, due to a variety of factors such as eye closure, eye occlusion, an...

Pre-emptive shadows: eliminating the blinding light from projectors
Users interacting with front-projected displays often work between the projector and the display surface. This causes undesirable projection on the user as well as temporary blind...
