CHARACTER RECOGNITION APPARATUS AND METHOD

摘要

According to one embodiment, a character recognition apparatus includes a first generation unit, an estimation unit, a second generation unit and a search unit. The first generation unit generates a user dictionary that a preferred character is registered. The estimation unit estimates a first separation between characters based on one or more of a layout of a target text and marking information. The second generation unit generates a lattice structure, by estimating character segments being expressed by strokes based on the first separation. The search unit searches, if the lattice structure includes the path corresponding to the preferred character, the lattice structure for a path to obtain a character recognition result.

1. A character recognition apparatus comprising:
a first generation unit configured to generate a user dictionary in which a character is registered as a preferred character, by extracting the character from at least one of text data items created by a user or used by the user; an estimation unit configured to estimate a first separation between characters based on at least one of a layout of a target text and marking information, the target text being a text for a recognition processing, the marking information relating to a marking attached to the target text; a second generation unit configured to generate a lattice structure, by estimating character segments which are expressed by strokes based on the first separation, the lattice structure being formed by the character segments and paths between the character segments and relating to a first character string included in a block providing the layout; and a search unit configured to, if the lattice structure includes a path corresponding to the preferred character, search the lattice structure for the path to obtain a character recognition result.
