Two-dimensional Picture Grammar models
2008 Second UKSIM European Symposium on Computer Modeling and Simulation, 2008A new theoretical model of grammatical picture generation called extended 2D context-free picture grammar (E2DCFPG) generating rectangular picture arrays of symbols is introduced. This model which allows variables in the grammar and uses the squeezing mechanism of forming the picture language over terminal symbols, is an extension of the pure 2D ...

Abstract Random context picture grammars (RCPGs) have become established as a method of syntactic picture generation. They are context-free grammars with regulated rewriting, where the application of a rule in the grammar is regulated by two sets of variables, the so-called permitting and forbidding context sets.

Terminal weighted grammars and picture description
Computer Vision, Graphics, and Image Processing, 1985Motivated by the idea of describing parquet deformations using grammars and also of describing an infinite number of terminals starting with only a finite set, this paper defines a terminal weighted grammar, where the terminal generated at any step of a derivation is defined as a function of time.

Writing grammar into the bigger picture
Primary Teacher Update, 2013Having looked at how to teach each building block of grammar, Liz Aitken puts it in wider context to help children write well, for a purpose and in an appropriate style.

Toward motion picture grammars
1997We are interested in processing video data for the purpose of solving a variety of problems in video search, analysis, indexing, browsing and compression. Instead of concentrating on a particular problem, in this paper we present a framework for developing video applications.

P Systems with 2D Picture Grammars
2011 Sixth International Conference on Bio-Inspired Computing: Theories and Applications, 2011In formal language theory of two-dimensions, 2D picture grammars are powerful tools to generate picture languages. In this work, we incorporate the idea of membrane systems (also called P systems) into 2D picture grammars, thus introducing a new kind of picture language generating devices, named P systems with 2D picture grammars.

TABLE-DRIVEN CONTEXT-FREE PICTURE GRAMMARS
International Journal of Foundations of Computer Science, 2007Random context picture grammars (rcpgs) are a method of syntactic picture generation. The productions of such a grammar are context-free, but their application is regulated—permitted or forbidden—by context randomly distributed in the developing picture.
