Claim 14:
15. A computerized system comprising a processor that is configured to:
obtain an acquired face signature and an acquired quality metadata indicative of a quality of the acquired face signature, the acquired face signature is a face signature of a captured face of an acquired person, the captured face is captured in an acquired image, wherein a size of the acquired face signature is smaller than a size of visual information of the captured face in the acquired image; wherein the acquired quality metadata is calculated based on at least one of (a) a pose of the captured face, (b) a yaw value of the captured face, (c) one or more facial attributes of the captured face, (d) a sharpness of the acquired image, (e) a size of the captured face within a cropped image generated by cropping the acquired image, or (f) a resolution of the acquired image;
perform a search related determination, based on the acquired quality metadata, of whether to search a history database for at least one similar reference face signature that is similar to the acquired face signature; wherein the history data base stores a mapping between reference face signatures, person identifiers, and appearance metadata;
search the history database, when determining to search the history database, for the at least one similar reference face signature that is similar to the acquired face signature;
perform an update related determination, based on an outcome of the search and on the acquired quality metadata, of whether to update the history database to reflect the capture of the face signature;
perform a first type of update when finding the at least one similar reference face signatures and determine to update the history database; and
perform a second type of update of the history database when not finding any similar reference face signature and determine to update the history database, wherein the search related determination requires first minimal quality level associated with the acquired face signature, wherein the update related determination required a second minimal quality level associated with the acquired face signature, wherein the first minimal quality level equals the second quality level.
