2-D EAG Method for the Recognition of Hand-Printed Chinese Characters

A method, called Two-Dimensional Extended Attribute Grammars (2-DEAGs). for the recognition ofhand-printed Chinese characters is presented. This method uses directly two dimensional information, and pro-vides a scheme for dealing with various kinds of specific cases in a uniform way. In this method, componentsare drawn in guided and redundant way and reductions are made level by level just in accordance with the com-ponent combination relations of Chinese characters. The method provides also polysemous grammars,coexisting grammars and structure inferrings which constrain redundant recognition by comparison among similarcharacters or components and greatly increase the tolerance ability to distortion.
