Abstract
A character recognition device includes image input unit that receives an image, character region detection unit that detects a character region in the image, character region separation unit that separates the character region on a character-by-character basis, character recognition unit that performs character-by-character recognition on the characters present in separated regions and outputs one or more character recognition result candidates for each character, first character string transition data creation unit that receives the candidates, calculates weights for transitions to the candidates and creates first character string transition data based on a set of the candidates and the weights, and WFST processing unit that sequentially performs state transitions based on the first character string transition data, accumulates weights in each state transition and calculates a cumulative weight for each state transition, and outputs one or more state transition results based on the cumulative weight.
