This paper describes the architecture of a lexicon system called READLEX dealing with requirements of both text recognition and text analysis in document analysis. In order to meet these requirements, we have develope...
A hybrid radial basis function networklhidden Markov model off-line handwritten wordrecognition system is presented. It is inspired from methods used originally in the field of automatic speech recognition The hidden...
