A fuzzy hierarchical attributed graph approach for handwritten Egyptian hieroglyphs description and matching

For a complex writing such as Egyptian hieroglyphs, combining the works done in hierarchical modeling and fuzzy grammar definitions seems natural. This paper introduces the hierarchical-fuzzy-attributed graph (FHAG), extended from fuzzy-attributed graph, which models attributes by fuzzy-tree grammar. We give a formal definition of FHAGs and introduce adapted measurements for matching them. FHAG is then integrated in a recognition system based on single models comparisons for handwritten Egyptian hieroglyphs.
