<p>A method and apparatus for dynamically switching between fonts or groups of fonts in an automatic character recognition system (10). The feature vector that the recognition system produces for each character on a document is normalized to unit length (24) and projected onto a set of eigenvectors (28). A memory (26) in the character recognition system stores several sets of eigenvectors, each set corresponding to a particular character font. A switch character which is included between a first and second group of characters triggers the selection of the appropriate set of eigenvectors for the succeeding font. </p> |
