Splines and Wavelets: New Perspectives for Pattern Recognition

Michaël Unser

We provide an overview of spline and wavelet techniques with an emphasis on applications in pattern recognition. The presentation is divided in three parts. In the first one, we argue that the spline representation is ideally suited for all processing task ...

Splines: A Perfect Fit for Medical Imaging

Michaël Unser

Splines, which were invented by Schoenberg more than fifty years ago, constitute an elegant framework for dealing with interpolation and discretization problems. They are widely used in computer-aided design and computer graphics, but have been neglected i ...

Function approximation on triangular grids: some numerical results using adaptive techniques

Luca Formaggia

Applications of mesh adaptation techniques could be found in the numerical solution of PDE's or in the optimal triangulation of surfaces for shape representation or graphic display. The scope of this work is to verify through numerical experiments the effe ...

Optimising and extending the geometrical modeller of a physics simulation framework

The design of highly complex particle detectors used in High Energy Physics involves both CAD systems and physics simulation packages like GEANT4. GEANT4 is able to exchange detector geometries with CAD systems, conforming to the Standard for the Exchange ...

A flexible architecture for virtual humans in networked collaborative virtual environments

Daniel Thalmann

Complex virtual human representation provides more natural interaction and communication among participants in networked virtual environments, hence it is expected to increase the sense of being together within the same virtual world. We present a flexible ...

Hair animation with collision detection

Daniel Thalmann

An efficient method is proposed for hair animation. The movement of hairs is modeled by simplified physical simulations. In particular the method can treat successfully collisions between hair and a human body or other objects, which provides realistic hai ...

A general algorithm for 3-D shape interpolation in a facet-based representation

Daniel Thalmann

Concerned with interpolation between two objects defined using a faceted representation. The interpolation function is not examined, but the paper emphasizes the problem of correspondence between the two given key drawings. The problem is much more complex ...
