Abstract
A feature amount obtained from an image group for registration is stored as dictionary data in a memory. When an input image group constituted of a plurality of images is supplied to be collated with the dictionary data, the images constituting the input image group are classified based on a specific classification standard, a feature amount obtained from each of the classified image groups is collated with the feature amount stored as the dictionary data in the memory, and a result of the collation of all the input image groups with the dictionary data is determined based on a result of integrating a plurality of collection results of the classified image groups with the dictionary data.
Claims24
A method for collating biometric information, comprising:
- storing dictionary data based on an image group for registration in a memory;
- inputting the image group constituted of a plurality of images;
- classifying the input image group into a plurality of image subgroups based on a specific standard;
- collating each classified image subgroup with the dictionary data stored in the memory;
- and
- determining a result of collation of biometric information contained in each image of the input image group with the dictionary data based on a result of the collation of each classified image subgroup with the dictionary data.
A device for collating biometric information, comprising:
- a memory which stores dictionary data based on an image group for registration;
- an image input section which inputs the image group constituted of a plurality of images;
- a classification section which classifies the image group input by the image input section into a plurality of image subgroups based on a specific standard;
- a collation section which collates each image subgroup classified by the classification section with the dictionary data stored in the memory;
- and
- a determination section which determines a result of collation of biometric information contained in each image of the image group input by the image input section with the dictionary data based on a result of the collation of each image subgroup classified by the classification section with the dictionary data.
