Holistic-analytical recognition of handwritten text

摘要

In a combined holistic and analytic recognition system, a holistic recognition module recognizes an input word or phrase image by matching an input string of character features for the whole word or phrase against a string of prototype features for a plurality of reference words in a lexicon. This yields a holistic answer list of candidates for the input word or phrase. Based on each answer in the holistic answer list, the holistic recognition module creates segmentation hypotheses for each character in an answer. The analytical recognition module uses segmentation hypotheses from the holistic answer list to cut the image of the input string of characters into individual character images and to produce an analytical answer list. The holistic answer list and the analytic answer list are compared to find the best answer from the two lists.
