Contour Retrieval and Matching by Affine Invariant Fourier Descriptors
In the image plane, a 3 Dimensional movement of planar rigid object can be represented satisfactory by an affine motion of his boundary (the exterior contour) which we assume to b...

Head Pose Estimation from Passive Stereo Images
We present an algorithm to estimate the 3D pose (location and orientation) of a previously unseen face from low-quality range images. The algorithm generates many pose candidates ...

Wrapping snakes for improved lip segmentation
A key step in the process of lip-reading is determining the shape of the speaker’s lips. This has previously been achieved through an energy method known as “snakes”, howeve...

A wave-based anisotropic quadrangulation method
This paper proposes a new method for remeshing a surface into anisotropically sized quads. The basic idea is to construct a special standing wave on the surface to generate the gl...
