PATTERN COLLATION DEVICE AND PATTERN COLLATING METHOD THEREOF, AND PATTERN COLLATION PROGRAM |
摘要 |
A pattern collation device for comparing and collating graphic forms includes a deformation estimating unit for estimating deformation generated in a graphic form to be examined which is a graphic form as an object of examination based on information about a feature point indicative of features in each of the graphic form to be examined in question and a model graphic form as a graphic form based on which comparison is made, a deformation correcting unit for correcting the graphic form to be examined in question based on information about the deformation estimated by the deformation estimating unit and a similarity determining unit for comparing the graphic form to be examined whose deformation is corrected by the deformation correcting unit with the model graphic form as a graphic form based on which comparison is made to calculate similarity therebetween.
