Representation of interwoven surfaces in 2 1/2 D drawing
The state-of-the-art in computer drawing programs is based on a number of concepts that are over two decades old. One such concept is the use of layers for ordering the surfaces i...

Geographic representation in spatial analysis
Spatial analysis mostly developed in an era when data was scarce and computational power was expensive. Consequently, traditional spatial analysis greatly simpli

A theory of phase-sensitive rotation invariance with spherical harmonic and moment-based representations
This paper describes how phase-sensitive rotation invariants for three-dimensional data may be obtained. A “bispectrum” is formulated for rotations, and its properties are der...

Compressed Representations of Permutations, and Applications
We explore various techniques to compress a permutation π over n integers, taking advantage of ordered subsequences in π, while supporting its application π(i) and the applicat...

Motor planning and sparse motor command representation
The present article proposes a novel computational approach to the motor planning. In this approach, each motor command is represented as a linear combination of prefixed basis p...
