Constructing Word-Based Text Compression Algorithms
Text compression algorithms are normally defined in terms of a source alphabet of 8-bit ASCII codes. We consider choosing to be an alphabet whose symbols are the words of Englis...

A Geometrical Heuristic for Drawing Concept Lattices
Abstract. Concept lattices are used in formal concept analysis to represent data conceptually so that the original data are still recognizable. Their line diagrams should re ect th...

Visibility Graphs and Oriented Matroids
We describe a set of necessary conditions for a given graph to be the visibility graph of a simple polygon. For every graph satisfying these conditions we show that a uniform rank ...

A coaxial optical scanner for synchronous acquisition of 3D geometry and surface reflectance
Shifted sinusoidal illumination patterns are useful for appearance capture because they simultaneously separate local and non-local reflections and allow the recovery of surface g...

Manifold bootstrapping for SVBRDF capture
Manifold bootstrapping is a new method for data-driven modeling of real-world, spatially-varying reflectance, based on the idea that reflectance over a given material sample forms...

Star-contours for efficient hierarchical self-collision detection
Collision detection is a problem that has often been addressed efficiently with the use of hierarchical culling data structures. In the subproblem of self-collision detection for ...

Fabricating spatially-varying subsurface scattering
Many real world surfaces exhibit translucent appearance due to subsurface scattering. Although various methods exists to measure, edit and render subsurface scattering effects, no...
