1. A person verification device comprising:
at least one memory storing instructions; and
at least one processor configured to execute the instructions to:
estimate, from an image of a person, respective existence probabilities of human body parts of the person;
normalize the respective existence probabilities based on an existence probability of a whole human body part of the person;
estimate, from the image, a plurality of weights of the human body parts of the person corresponding to the normalized respective existence probabilities;
create a feature for verification by weighting an image feature extracted from the image with the estimated weights; and
compare the created feature for verification and a prestored verification feature.
