Patent number: 10482354Abstract: According to an embodiment, a creation device creates a code table including a plurality of code words. A recognition device identifies a code word represented by a code image based on a result of character recognition of the code image formed on an object, the code table, and a confusion matrix preliminarily created. The confusion matrix represents probabilities that characters are recognized when the recognition device performs character recognition on an image. The creation device includes a change unit, an evaluation value calculation unit, and a control unit. The change unit changes the code table. The evaluation value calculation unit calculates an evaluation value of the changed code table using the confusion matrix. The control unit causes the change of the code table and the calculation of the evaluation value to be repeated such that the evaluation value becomes small.Type: GrantFiled: September 21, 2017Date of Patent: November 19, 2019Assignees: Kabushiki Kaisha Toshiba, Toshiba Digital Solutions CorporationInventor: Tomohisa Suzuki
