Image data verification apparatus, the image data verification method, and storage medium storing an image processing program verification data

摘要

PROBLEM TO BE SOLVED: To accurately perform the collation of images considering a rotation deviation between registered image data and collation image data and to shorten time required for the collation in an image data collation device for collating fingerprint image data for instance. SOLUTION: For a collation fingerprint image B rotationally converted by respective rotation deviation correction angles θm (=0 deg., 1 deg., -1 deg., 2 deg., -2 deg., 3 deg., -3 deg.,..., k deg., -k deg. [m = the integer of 1 to k×2+1 and k=1]) including the rotation deviation correction angle θ1=0 deg., by alternately executing the two kinds of collation processings that are the collation processing in the case of arranging a template area Ai inside a registered fingerprint image A and the collation processing in the case of arranging the template area Bi inside the rotation-converted collation fingerprint image B, the fingerprint collation of the same person/the same finger provided with the rotation deviation is performed. The possibility of obtaining collation matching is raised at the smaller rotation deviation correction angle θm, the arithmetic processing amount is reduced and collation time is shortened.
