Grammatical Inference of Dashed Lines

摘要

Dashed lines are a common, and semantically important, element in line drawings. This paper deals with the inference of a dashed lines' grammar, given a stream of graphical symbols. A method is presented, based on syntactical pattern recognition, capable of inferring arbitrary grammars without a priori knowledge. A detailed complexity-analysis of the developed algorithms is presented, as well as experiments demonstrating the usefullness of our method.
