Abstract

This paper describes a character recognition system that uses first order Hidden Markov models to treat multifont printed text. The text is first segmented into characters from where features are deduced and quantized. The Modified Viterbi Algorithm is the recognition method chosen. Depending on choice, the system outputs strings of characters, supposedly words, or the string is first matched against a dictionary or the string is passed through a Viterbi net with the output being the recognized word. In tests with deterministic decision trees, the performance is promising in multifont optical character recognition.
