In contrast to the situation of typically developing children, they use different modalities for comprehension (auditory) and expression (visual). This study explored the ability of three- and...
متن کاملLearning of Structural Descriptions of Graphic Symbols Using Deformable Template Matching
Accurate symbol recognition in graphic documents needs an accurate representation of the symbols to be recognized. If structural approaches are used for recognition, symbols have to be described in ternu of their shape, using structural relationships among extracted features. Unlike statistical pattern recognition, in structutul methods, slwbols are usually manually deJined from expertise knowl...
متن کاملSymbols Recognition System for Graphic Documents Combining Global Structural Approaches and Using a XML Representation of Data
In this paper we present a symbols recognition system for graphic documents, based on a combination of global structural approaches. Our system allows to extract components and their loops, with their inclusion and neighboring links. So, it is possible to construct different graph types according to the considered recognition problem. Our system uses an XML representation of data, which allows ...
متن کاملChildren's identification of graphic symbols representing four basic emotions: comparison of Afrikaans-speaking and Sepedi-speaking children.
