Abstract

Considering digital ink traces as plane curves provides a useful framework for handwriting recognition. Characters may be represented as parametric curves approximated by certain truncated orthogonal series, mapping symbols to the low-dimensional vector space of series coefficients. Many useful properties are obtained in this representation, allowing fast recognition based on small training sets. The beauty of this framework is that a single, coherent view leads to highly efficient methods with a high recognition rate. Furthermore, these truncated orthogonal series are subject to all the geometric techniques of symbolic-numeric polynomial algorithms.
