Abstract
In order to obtain a low computational cost
method (or rough classification) for automatic handwritten
characters recognition, this paper proposes a
combined system of two feature representation methods
based on a vector field: one is autocorrelation
matrix, and another is a low frequency Fourier expansion.
In each method, the similarity is defined
as a weighted sum of the squared values of the inner
product between input pattern feature vector and the
reference pattern ones that are normalized eigenvectors
of KL (Karhunen-Loeve) expansion. This paper
also describes a way of deciding the weight coefficients
using a simple linear regression model, and shows the
effectiveness of the proposed method by illustrating
some experimentation results for 3036 categories of
handwritten Japanese characters. |
