Diacritical processing for unconstrained, on-line handwriting recognition using a forward search

摘要

Handwritten ink is scanned to identify potential diacriticals. A list of diacriticals (19) is generated by traversing the ink. Potential diacritical-containing characters are processed by scoring them with and without a diacritical to generate a first and second score. The first score is compared to the second score to in order to make a decision as to which variant of the potential diacritical-containing character produced a highest score. The highest score is used as a score for a theory and the decision is recorded. A data structure (50) is added to the theory. Each data unit in the data structure (50) corresponds to an entry in the list of diacriticals (19). As a new theory is created by propagation, contents of the data structure (50) are copied into the new theory. Thus, the data structure (50) is used to ensure that all handwritten ink is used and is used only once.
