Patent ID: 8103124

Claim:
A registration apparatus comprising: a control section including: a processor, an embossment section that is configured to emboss a physical trait, of an imaged object, on a first image of the imaged object, a pattern extraction section that is configured to extract the physical trait as a line-shaped pattern, a detection section that is configured to detect some or all of junction points, endpoints and turning points of the line-shaped pattern as feature points, a calculation section that is configured to: search a second image, upon which the physical trait has been embossed by the embossment section prior to embossing the physical trait on the first image, for a point corresponding to the position of each feature point detected from the first image, and obtain a representative value of position vectors drawn from the positions to the corresponding points as a positional difference, wherein the positional difference is between part of the physical trait on the first image that is processed and the corresponding part of the physical trait on the second image that was processed earlier than the first image, the physical trait being used for verification; and a connecting section that is configured to: correct, in accordance with the calculated positional difference, the position of the first image such that part of the physical trait on the first image is overlapped with the corresponding part of the physical trait on the second image, and connect the first corrected image to the second image; and a registration section that is configured to register the connected image in a storage medium.
