A. H. Toselli, M. Pastor, V. Romero, A. Juan, E. Vidal, and F. Casacuberta. Off-line and On-line Continuous Handwritten Text Recognition in PRHLT Group. In F. Pla, P. Radeva, and J. Vitrià, editors, Pattern Recognition: Progress, Directions and Applications, pages 146-161. Centre de Visió per Computador, 2006. ISBN 84-933652-6-2. The main purpose of this work is to provide a qualitative description of the current research area on Continuous Handwritten Text Recognition for both off-line and on-line cases, carried out by the Pattern Recognition and Human Language Technology (PRHLT) group of the "Instituto Tecnológico de Informática". A general overview of a handwriting recognition system is given, focussing specially on architectonic scheme. According to the case type (off-line and on-line), different preprocessing and feature extraction methods are briefly explained. Also, a short description about how the different linguistic levels: morphological, lexical and syntactical are modelled using the finite-state technology is dedicated. Finally, several fully functional prototype applications of handwriting recognition are presented.
