Classification: CPC B  G | IPC B  G

Claim 0:
1. An autonomous mobile device (AMD) comprising:
a camera;
one or more non-transitory memories storing computer-executable instructions; and
one or more processors to execute the computer-executable instructions to:
acquire a first image at a first time using the camera;
determine that a first portion of the first image depicts a first person;
determine, using a first neural network, a first feature vector, wherein the first feature vector is representative of one or more features of the first person as depicted in the first image;
generate first gallery data associated with a first user identifier, wherein the first gallery data comprises the first feature vector that is associated with the first person;
acquire a second image at a second time using the camera;
determine that a second portion of the second image depicts a second person;
determine, using the first neural network, a second feature vector, wherein the second feature vector is representative of one or more features of the second person as depicted in the second image;
determine, based on the first feature vector and the second feature vector, a similarity value that is indicative of similarity between the first person and the second person; and
determine, based at least in part on the similarity value exceeding a first threshold value, that the second person is associated with the first user identifier.
