Abstract
A weight estimation unit estimates, from a person's image in which a person is included, a weight of a human body part of the person in accordance with an existence probability of the human body part of the person. A feature creation unit creates a feature for verification based on a weight of the person's image and a weight estimated by the weight estimation unit. A verification feature storage unit stores a feature of the person who is the object of verification as a verification feature. A person verification unit compares the feature for verification created by the feature creation unit and the verification feature stored in the verification feature storage unit.
Claims12
A person verification device comprising:
- at least one memory configured to store instructions;
- and
- at least one processor configured to execute the instructions to:
- estimate, from a person's image in which a person is included, a weight of a human body part of the person in accordance with an existence probability of the human body part;
- extract an image feature from the person's image;
- create a feature for verification by weighting the extracted image feature with the estimated weight;
- and
- compare the created feature for verification and a verification feature.
A person verification method comprising:
- estimating, by a processor and from a person's image in which a person is included, a weight of a human body part of the person in accordance with an existence probability of the human body part;
- extracting, by the processor, a feature for verification based on the person's image and the estimated weight;
- creating, by the processor, a feature for verification by weighting the extracted image feature with the estimated weight;
- comparing, by the processor, the created feature for verification and a verification feature;
- and
- outputting, by the processor, a result of the comparison.
A non-transitory computer readable medium configured to store a program for causing a computer to perform processing of:
- estimating, from a person's image in which a person is included, a weight of a human body part of the person in accordance with an existence probability of the human body;
- extracting a feature for verification based on the person's image and the estimated weight;
- creating a feature for verification by weighting the extracted image feature with the estimated weight;
- comparing the created feature for verification and a verification feature;
- and
- outputting a result of the comparison.
