Claim 17:
18. A method, comprising:
partitioning a first image data representative of at least a portion of a first agent into:
a first partition that includes a first portion of the first image data corresponding to at least a portion of a head region of the first agent represented in the first image data; and
a second partition that includes a second portion of the first image data that is at least partially different than the first portion;

generating a first signature corresponding to the first portion;
generating a second signature corresponding to the second portion;
comparing the first signature with a first stored signature corresponding to a stored image data representative of the head region of a second agent represented in the stored image data to determine a first similarity score between the first signature and the first stored signature;
comparing the second signature with a second stored signature corresponding to a second portion of the second agent represented in the stored image data to determine a second similarity score between the second signature and the second stored signature, wherein the stored image data is selected from at least one of:
a missing agent patterns data store of agent patterns of agents that are missing; or
a non-tracked agent patterns data store of agents that are not currently tracked;

determining, based at least in part on the first similarity score and the second similarity score, that the first agent represented in the first image data is the second agent represented in the stored image data; and
including an identification of the agent represented in stored image data in a list of a plurality of candidate agents that are potentially the agent represented in the first image data such that the list only includes agents that are determined to potentially be the agent represented in the first image data.
