Abstract
A character recognition apparatus includes a stroke extracting unit, a noise-candidate extracting unit, a generating unit, a unit, and a specifying unit. The stroke extracting unit extracts multiple strokes from a recognition target. The noise-candidate extracting unit extracts noise candidates from the strokes. The generating unit generates multiple recognition result candidates obtained by removing at least one of the noise candidates from the recognition target. The unit performs character recognition on the recognition result candidates and obtains recognition scores. The specifying unit uses the recognition scores to specify a most likely recognition result candidate from the recognition result candidates as a recognition result.
Claims12
A character recognition apparatus comprising:
- a processor configured to:
- extract a plurality of strokes from a recognition target;
- extract noise candidates from the plurality of strokes;
- generate a plurality of recognition result candidates obtained by removing at least one of the noise candidates from the recognition target;
- perform character recognition on the plurality of recognition result candidates and calculate recognition scores for each of the plurality of recognition result candidates;
- and
- use the recognition scores to specify a most likely recognition result candidate from the plurality of recognition result candidates as a recognition result.
A character recognition apparatus comprising:
- a processor configured to:
- extract a plurality of strokes from a recognition target;
- extract noise candidates from the plurality of strokes;
- generate a plurality of recognition result candidates obtained by removing at least one of the noise candidates from the recognition target;
- and
- select recognition result candidates from the plurality of recognition result candidates, each of the selected recognition result candidates having a recognition score higher than a predetermined value, the recognition score indicating a probability of recognition, and specify a recognition result candidate having the largest number of strokes from the selected recognition result candidates as a recognition result.
A character recognition processing system comprising:
- a character recognition apparatus;
- and
- a user-writing-information acquiring device,
- wherein the character recognition apparatus includes a processor configured to:
- extract a plurality of strokes from a recognition target obtained from the user-writing-information acquiring device,
- extract noise candidates from the plurality of strokes,
- generate a plurality of recognition result candidates obtained by removing at least one of the noise candidates from the recognition target,
- calculate recognition scores for each of the plurality of recognition result candidates
- perform character recognition on the plurality of recognition result candidates and calculate recognition scores for each of the plurality of recognition result candidates,
- use the recognition scores to specify a most likely recognition result candidate from the plurality of recognition result candidates as a recognition result, and
- output the recognition result specified by the processor.
A non-transitory computer readable medium storing a program causing a computer to execute a process comprising:
- extracting a plurality of strokes from a recognition target;
- extracting noise candidates from the plurality of strokes;
- generating a plurality of recognition result candidates obtained by removing at least one of the noise candidates from the recognition target;
- performing character recognition on the plurality of recognition result candidates and calculating recognition scores for each of the plurality of recognition result conditions;
- and
- using the recognition scores to specify a most likely recognition result candidate from the plurality of recognition result candidates as a recognition result.
