The highest fidelity representations of realistic real-world materials currently used comprise Bidirectional Texture Functions (BTF). The BTF is a six dimensional function dependi...
An algorithm for automatic modelling of wavelet coefficients from context properties is presented. The algorithm is used to implement an image coder, in order to demonstrate its i...
This and the accompanying paper present an overview of the face and body animation object in the MPEG-4 Version 2 standard. The MPEG-4 standard includes the representation, compre...
Since years the market of mobile navigation systems is growing enormously. Within this paper the goals and first results of the joint project "Mobile Navigation with 3D City ...
The paper presents a novel coding technique based on approximate geometry for images taken from arbitrary recording positions around a 3-D scene. Such data structures occur in ima...
