TimeSlider: An Interface to Specify Time Point
This paper introduces TimeSlider, a user interface technique that allows the user to specify time points. TimeSlider is a kind of slider whose time scale is nonlinear and which mo...

Kinetic collision detection between two simple polygons
We design a kinetic data structure for detecting collisions between two simple polygons in motion. In order to do so, we create a planar subdivision of the free space between the ...

Using Multiple-Hypothesis Disparity Maps and Image Velocity for 3-D Motion Estimation
In this paper we explore a multiple hypothesis approach to estimating rigid motion from a moving stereo rig. More precisely, we introduce the use of Gaussian mixtures to model cor...

Face Shape Reconstruction from Image Sequence Taken with Monocular Camera using Shape Database
We propose a method for reconstructing 3D face shape from a camera, which captures the object face from various viewing angles. In this method, we do not directly reconstruct the ...
