Applications of irradiance tensors to the simulation of non-Lambertian phenomena
We present new techniques for computing illumination from non-diffuse luminaires and scattering from non-diffuse surfaces. The methods are based on new closed-form expressions d...

Isometry-invariant Matching of Point Set Surfaces
Shape deformations preserving the intrinsic properties of a surface are called isometries. An isometry deforms a surface without tearing or stretching it, and preserves geodesic d...

Shared Sampling for Real-Time Alpha Matting
Image matting aims at extracting foreground elements from an image by means of color and opacity (alpha) estimation. While a lot of progress has been made in recent years on impro...

On the Fly Authentication and Signature Schemes Based on Groups of Unknown Order
Abstract. In response to the current need for fast, secure and cheap public-key cryptography, we propose an interactive zero-knowledge identification scheme and a derived signature...
