Information processing apparatus and non-transitory computer readable medium storing program

1. An information processing apparatus comprising:

a first character recognition section that performs character recognition of an input image on an assumption that a character in the input image belongs to a first character type and outputs a first character recognition result being a result of the character recognition;

a second character recognition section that performs character recognition of the input image on an assumption that the character in the input image belongs to a second character type and outputs a second character recognition result being a result of the character recognition, the second character type being a set obtained by adding at least one or more characters which do not belong to the first character type to a set of characters belonging to the first character type; and

a matching section that performs matching of the first character recognition result with the second character recognition result, and, in a case where it is found that the first character recognition result does not match with the second character recognition result by the matching, rejects the first character recognition result.

2. The information processing apparatus according to claim 1 ,

wherein the second character recognition section outputs a plurality of second character recognition results different from each other, for one input image,

the matching section matches each of the plurality of second character recognition results different from each other with the first character recognition result, and, in a case where it is found that all the plurality of second character recognition results different from each other do not match with the first character recognition result by the matching, rejects the first character recognition result.

3. The information processing apparatus according to claim 1 , further comprising:

a third character recognition section that performs character recognition of the input image on an assumption that the character in the input image belongs to a third character type and outputs a third character recognition result being a result of the character recognition, the third character type being a set obtained by adding at least one or more characters which do not belong to the first character type and the second character type to a set of characters belonging to the first character type,

wherein the matching section performs matching of the first character recognition result with the second character recognition result and matching of the first character recognition result with the third character recognition result, and, in a case where it is found that the first character recognition result does not match with any of the second character recognition result and the third character recognition result by the matching, rejects the first character recognition result.

4. An information processing apparatus comprising:

a first character recognition section that performs character recognition of an input image on an assumption that a character in the input image belongs to a first character type, and outputs a first character recognition result being a result of the character recognition and certainty of the first character recognition result;

a second character recognition section that performs character recognition of the input image on an assumption that the character in the input image belongs to a second character type and outputs a second character recognition result being a result of the character recognition, the second character type being a set obtained by adding at least one or more characters which do not belong to the first character type to a set of characters belonging to the first character type; and

a receiving section that receives an input of the character recognition result of the input image by a person;

a first matching section that performs matching of the first character recognition result with the second character recognition result;

a section that, in a case where it is found that the first character recognition result matches with the second character recognition result by the matching of the first matching section and the certainty is equal to or greater than a threshold, outputs the first character recognition result as a final character recognition result on the input image; and

a second matching section that, in a case where it is found that the first character recognition result does not match with the second character recognition result by the matching of the first matching section or the certainty is smaller than the threshold, performs matching of the first character recognition result with the character recognition result received by the receiving section by the person, and obtains and outputs the final character recognition result based on a result of the matching.

5. A non-transitory computer readable medium storing a program causing a computer to function as:

a first character recognition section that performs character recognition of an input image on an assumption that a character in the input image belongs to a first character type and outputs a first character recognition result being a result of the character recognition;

a second character recognition section that performs character recognition of the input image on an assumption that the character in the input image belongs to a second character type and outputs a second character recognition result being a result of the character recognition, the second character type being a set obtained by adding at least one or more characters which do not belong to the first character type to a set of characters belonging to the first character type; and

a matching section that performs matching of the first character recognition result with the second character recognition result, and, in a case where it is found that the first character recognition result does not match with the second character recognition result by the matching, rejects the first character recognition result.
