Abstract. We review the field of offline cursive word recognition. We mainly deal with the various methods that were proposed to realize
the core of recognition in a word recognition system. These methods are discussed in view of the two most important properties
of such a system: the size and nature of the lexicon involved, and whether or not a segmentation stage is present. We classify
the field into three categories: segmentation-free methods, which compare a sequence of observations derived from a word image
with similar references of words in the lexicon; segmentation-based methods, that look for the best match between consecutive
sequences of primitive segments and letters of a possible word; and the perception-oriented approach, that relates to methods
that perform a human-like reading technique, in which anchor features found all over the word are used to boot-strap a few
candidates for a final evaluation phase.
Key words:Offline – Cursive – Handwritten – Word recognition – Segmentation – Survey
