A spatio-temporal perceptron for on-Line handwritten character recognition

Abstract

The objective of this work is the application of the spatio-temporal multilayer perceptron (ST-MLP) developed in our laboratory to the recognition of on-line handwritten characters. The ST-MLP integrates a spatio-temporal data coding defined in the complex domain. Starting from the stroke of a character produced by a digitizing tablet, we conduct the recognition process in two steps. This procedure which is classic in this domain, consist of a preprocessing step and a recognition one. The first step (segmentation step), identifies some elementary (basic) lines, called primitives, from the stroke of the character. Then we utilise the ST-MLP to recognize the traced character from the primitives provided.
