Achievements, Challenges, and Evolution. 8th International Workshop, GREC 2009. Selected Papers PY 2010 BP 187 EP 198 VL 6020 DI 10.1007/978-3-642-13728-0_17 AB In this paper we propose a new approach to recognize symbols by the use of a concept lattice. We propose to build a concept lattice in terms of graphical patterns. Each model symbol is decomposed in a set of composing graphical patterns taken as primitives. Each one of these primitives is described by boundary moment invariants. The obtained concept lattice relates which symbolic patterns compose a given graphical symbol. A Hasse diagram is derived from the context and is used to recognize symbols affected by noise. We present some preliminary results over a variation of the dataset of symbols from the GREC 2005 symbol recognition contest. ER
