Abstract
To efficiently process character blocks including mutually contacting characters by an optical character reader, not only are histograms prepared in a known manner but after candidate positions are determined from a histogram according to a specified set of criteria, their combinations are considered and the characters which are recognized corresponding to each combination of candidate positions are used to obtain average similarity values. Spellcheck routines and these average similarity values are considered together to identify characters which are contacting each other.
