Offline cursive script word recognition ? a survey

We review the eld of oine 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 eld into three categories: segmentation-free methods, which compare a sequence of observations de- rived 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 pri- mitive 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 nal evaluation phase.
