Paper Abstract

This paper presents major achievements made towards the development of a high-speed optical character recognition (OCR) workstation for characters of various fonts and sizes. The system is based upon an efficient feature extraction concept centred around an edge-vectorization technique. The resulting edges are mapped into a feature space from where a binary feature vector is built and subsequently fed to a standard statistical Bayesian classifier. The technique has been demonstrated on an IBM-PC/XT (without coprocessor) to operate at least 25 times the speed of conventional OCR techniques, achieving a 100% recognition rate with learned characters and 87% with unlearned.
