ABSTRACT:
Processing of handwritten patterns, for example, inputting of complex characters, such as Kanji, into a word processor involves a balance between an algorithmic part and a disambiguation part. Application of routines uniformly during the algorithmic part deliberately results in confusion sets of characters which are subsequently differentiated during the disambiguation part. Balance between the two parts permits a flexibility to accommodate differences in writing styles, while application of routines customized to the established character patterns permits the unique solution necessary for accurate recognition of a character.
