An Associative Perception-Action Structure Using a Localized Space Variant Information Representation
Abstract. Most of the processing in vision today uses spatially invariant operations. This gives efficient and compact computing structures, with the conventional convenient separa...

The Multidimensional Isotropic Generalization of Quadrature Filters in Geometric Algebra
In signal processing, the approach of the analytic signal is a capable and often used method. For signals of finite length, quadrature filters yield a bandpass filtered approxim...

On the Geometric Structure of Spatio-temporal Patterns
The structure of hypersurfaces corresponding to different spatio-temporal patterns is considered, and in particular representations based on geometrical invariants, such as the Ri...

Decision Complexity in Dynamic Geometry
Abstract. Geometric straight-line programs [5, 8] can be used to model geometric constructions and their implicit ambiguities. In this paper we discuss the complexity of deciding w...

Algebraic Methods for Optimization Problems
Abstract. We argue for the benefits of relations over functions for modelling programs, and even more so for modelling specifications. To support this argument, we present an ext...
