Abstract
According to one embodiment, a character recognition apparatus includes a detection unit and a recognition unit. The detection unit detects each character candidate from an image. The recognition unit recognizes each character candidate based on a plurality of character recognition dictionaries corresponding to a plurality of degrees of different character chipping.

A character recognition apparatus, comprising:
- a detection unit that detects each character candidate from an image;
- and
- a recognition unit that recognizes each character candidate based on a plurality of character recognition dictionaries corresponding to a plurality of degrees of different character chipping.
A character recognition method, comprising:
- detecting each character candidate from an image;
- and
- recognizing each character candidate based on a plurality of character recognition dictionaries corresponding to a plurality of degrees of different character chipping.
A character recognition apparatus that recognizes a character string in which a plurality of characters is arranged like a row, comprising:
- a hidden character string candidate detection unit that detects a character portion that may be hidden under circumstances in which a portion of the character string is hidden and sets the character portion as a hidden character string region candidate;
- a checking unit that checks whether any character is actually hidden by the hidden character string region candidate detected by the hidden character string candidate detection unit;
- and
- a recognition unit that performs recognition processing of the target character string based on a recognition result by the checking unit.
A character recognition method of recognizing a character string in which a plurality of characters is arranged like a row, comprising:
- detecting a character portion that may be hidden under circumstances in which a portion of the character string is hidden and setting the character portion as a hidden character string region candidate;
- checking whether any character is actually hidden by the detected hidden character string region candidate;
- and
- performing recognition processing of the target character string based on a recognition result.
A sorting apparatus that sorts an object on which sorting information indicating a sorting destination by a character string is marked based on the sorting information, comprising:
- a transfer unit that transfers the object;
- a reading unit that reads an image of the object transferred by the transfer unit;
- a character recognition unit that recognizes the character string indicating the sorting information from an image read by the reading unit;
- and
- a sorting unit that sorts the object based on the character string as the sorting information recognized by the character recognition unit, wherein
- the character recognition unit includes:
- a hidden character string candidate detection unit that detects a character portion that may be hidden under circumstances in which a portion of the character string is hidden and sets the character portion as a hidden character string region candidate;
- a checking unit that checks whether any character is actually hidden by the hidden character string region candidate detected by the hidden character string candidate detection unit;
- and
- a recognition unit that performs recognition processing of the target character string based on a recognition result by the checking unit.
