Title:
A living body feature vector extracting apparatus, a living body feature vector extraction method, and a living body feature vector extraction program
Document Type and Number:
Japanese Patent JP6167733
Kind Code:
B2
Abstract:
A device to extract a biometric feature vector includes: an obtain unit that obtains a biometric image; a unit to generate small region images that generates a plurality of small region images from the biometric image; a feature extractor that extracts biometric local feature amounts from the small region images; and a unit to generate a biometric feature vector that generates a biometric feature vector by combining the biometric local feature amounts in accordance with a predetermined rule, the biometric feature vector indicating a feature for identifying the biometric image, wherein the unit to generate small region images generates the plurality of small region images so that variability of biometric information amounts among the plurality of small region images is equal to or less than a predetermined value.
