Two-dimensional Picture Grammar models

2008 Second UKSIM European Symposium on Computer Modeling and Simulation, 2008
A 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 ...

Picture processing grammar and its applications

Information Sciences, 1971
A method for the description of the hierarchical structure of two-dimensional pictures is proposed. The model is called picture-processing grammar. It can be regarded as an extension of phrase-structure grammars to the two-dimensional case. A picture analysis program is described.

Writing grammar into the bigger picture

Primary Teacher Update, 2013
Having 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.

Mathematical picture grammar applied to script generation

Computer Graphics and Image Processing, 1977
In this paper a model of Mathematical Picture Grammar is described which has been developed and applied to generate the scripts of various Asian languages, e.g., Persian, Arabic, Urdu, Hindi, Bengala, and Kannada, using an IBM 1130 computer. The system of script generation has been developed through four stages.

Bag context picture grammars

Journal of Computer Languages, 2019
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, 1985
Motivated 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.
