PROBLEM TO BE SOLVED: To suppress a noise candidate, which is to be recognized as a character, from being removed as noise.SOLUTION: A character recognition apparatus 10 includes: a recognition object stroke group extraction unit 21 which extracts a plurality of strokes from a recognition object; a noise stroke candidate extraction unit 22 which extracts a noise candidate from the strokes; a character string configuration stroke group candidate generation unit 23 which generates recognition result candidates by deleting at least one noise candidate from the recognition object; and a maximum likelihood candidate output unit 25 which selects recognition result candidates having recognition scores, which indicate probability of recognition, higher than a predetermined value, from among the recognition result candidates, to specify a recognition result candidate with the maximum number of strokes from among the recognition result candidates, as a recognition result.SELECTED DRAWING: Figure 2 |
