Processing device and processing method

A processing device comprising:

• at least one hardware processor configured to implement:
• detecting a judgment use frame in input information from each of a plurality of registered forms serving as references;
• determining a representative frame by use of each of the detected judgment use frames;
• calculating each difference information between the determined representative frame and each of the judgment use frames;
• storing the each calculated difference information in association with each corresponding registered form;
• and
• determining whether the input information matches a first registered form by comparing a transformed judgement frame to the representative frame, and
• wherein the transformed judgement frame comprises the judgement frame transformed by a first transform coefficient of the representative frame.

A processing device comprising:

• at least one hardware processor configured to implement:
• obtaining a completed input form;
• detecting a judgment frame from the obtained completed input form;
• calculating input form difference information, which is difference information between the detected judgment frame and a predetermined representative frame;
• obtaining, from a memory in which each difference information between a judgment frame of each of a plurality of kinds of registered forms serving as references and the representative frame is stored, the difference information;
• judging an input form based on the input form difference information and the difference information, and
• comparing a transformed input form, which is obtained by transforming the input form by use of the input form difference information, with a representative form including the representative frame, and to judge whether or not the input form matches the representative form.

A processing method comprising:

• storing first difference information representing a difference between a judgment use frame in reference information and a representative frame in association with the reference information;
• based on second difference information representing a difference between a judgment frame in input information and the representative frame and on the first difference information having been stored, judging the input information by use of the reference information;
• and
• determining whether the input information matches a first registered form by comparing a transformed judgement frame to the representative frame,
• wherein at least one of the first difference information and the second difference information comprises transform coefficients of coordinate transformation, and
• wherein the transformed judgement frame comprises the judgement frame transformed by a first transform coefficient of the representative frame.
