Image processing apparatus and method

摘要

A processor configured to execute a process includes receiving image information including biometric information, extracting, from the image information, a first phase component image representing a phase component included in the image information, converting the image information into first frequency information and converts the first phase component image into second frequency information, extracting a first feature vector and a second feature vector respectively on the basis of amplitude information of the first frequency information and the second frequency information determined in advance, and combining the first feature vector and the second feature vector on the basis of a prescribed rule.

1. An image processing apparatus, comprising:
a processor configured to execute a process comprising:
receiving image information including biometric information;extracting, from the image information, a first phase component image representing a phase component included in the image information by
detecting edge information from the image information,converting the image information into first frequency information, andperforming inverse frequency conversion of first phase information included in the first frequency information into space information;converting the first phase component image into second frequency information;extracting a first feature vector and a second feature vector respectively based on amplitude information of the first frequency information and the second frequency information determined in advance; andcombining the first feature vector and the second feature vector based on a prescribed rule.
