Proceedings ArticleDOI
Color gamut transform pairs
TL;DR: A set of alternative models of the RGB monitor gamut based on the perceptual variables hue, saturation, and value (V) or brightness (L) are presented and algorithms for transforming between these models are derived.
Proceedings ArticleDOI
Blue screen matting
Alvy Ray Smith,James F. Blinn +1 more
TL;DR: The mathematics of constant color matting is presented and proven to be unsolvable as generally practiced, and constraints on the general problem that lead to solutions are demonstrated, or at least significantly prune the search space of solutions.
Proceedings ArticleDOI
Plants, fractals, and formal languages
TL;DR: An interesting class of procedural models of plants and trees is presented here which handles plant growth, sports an efficient data representation, and has a high “database amplification” factor.
Proceedings ArticleDOI
3-D transformations of images in scanline order
Ed Catmull,Alvy Ray Smith +1 more
TL;DR: In this article, the texture surface is transformed as a 2D image until it conforms to a projection of a polygon placed arbitrarily in 3D space, which is called a canonical polygon.
Journal ArticleDOI
Real-time language recognition by one-dimensional cellular automata
TL;DR: Pattern recognition by parallel devices is investigated by studying the formal language recognition capabilities of one-dimensional cellular automata, finding that nondeterministic bounded cellular Automata can recognize the context-free languages in real time.
