A structural model of shape deformation

摘要

An essential problem in handwriting recognition is how to cope with the complex shape deformation, and, therefore, the modeling of the deformation and metamorphosis (transformation of an instance of a class into an instance of the other class via continuous transformation) is a key to breaking through the difficulties in handwriting recognition. In this paper, on the basis of the structural feature extraction and description by Nishida, we present a model for structural deformation with simple, local operations that preserve the global structure of the shape. Furthermore, we present an experimental approach to analysis of metamorphosis of character shapes based on the structural deformation model.
