Recognizable Picture Languages and Polyominoes

2007
We consider the problem of recognizability of some classes of polyominoes in the theory of picture languages. In particular we focus our attention on the problem posed by Matz of finding a nonrecognizable picture language for which his technique for proving the non-recognizability of picture languages fails.

PLANG—A picture language schema for a class of pictures

Pattern Recognition, 1983
Abstract A picture language for a class of pictures made up of line-like curvilinear elements is presented. The description generated is natural and highly expressive. The description schema is shown to be capable of generating real-life pictures, interpreting pictures with real-life deformations and revealing structural information present in the ...

Stochastic languages for picture analysis

Computer Graphics and Image Processing, 1973
The concept of stochastic languages is introduced and major results are briefly reviewed. The use of stochastic languages for the description of noisy (ambiguous) pictorial patterns is demonstrated. A procedure for the estimation of production probabilities of a stochastic context-free language from sample strings is presented.

Picture Languages Generated by Assembling Tiles

Fundamenta Informaticae, 2009
We propose a new formalism for generating picture languages based on an assembly mechanism of tiles that uses rules having a context and a replacement site. More precisely, a picture language will be generated from a finite set of initial pictures by iteratively applying rewriting rules from a given finite set of rules, called a tiling rule system ...

The Language of Pictures

Abstract This chapter examines the Renaissance interest in hieroglyphics, and connects this interest to Philip Pullman’s creation of the dæmon. Knowledge of ancient Egyptian hieroglyphics, a writing system that had endured for millennia, was lost during the late Roman empire.
