Strategies to scan pictures with automata based on Wang tiles
RAIRO - Theoretical Informatics and Applications - Informatique Théorique et Applications, Volume 45 (2011) no. 1, p. 163-180

Wang automata are devices for picture language recognition recently introduced by us, which characterize the class REC of recognizable picture languages. Thus, Wang automata are equivalent to tiling systems or online tessellation acceptors, and are based like Wang systems on labeled Wang tiles. The present work focus on scanning strategies, to prove that the ones Wang automata are based on are those following four kinds of movements: boustrophedonic, “L-like”, “U-like”, and spirals.
