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 lowdimensional 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
more » ... cient methods with a high recognition rate. Furthermore, these truncated orthogonal series are subject to all the geometric techniques of symbolic-numeric polynomial algorithms.
