Patent ID: 7587068

Claim:
One or more processor-readable media having stored thereon processor-readable code including a database of face print image data corresponding to detected face regions within images acquired with an image acquisition device and digitally-stored, wherein the face print image data are stored within the media for access by a processor comprises: (a) an image data component including acquired digital image data including content data and unique identifiers corresponding to acquired digital images or face regions therein, or both; (b) an identity data component including an identification listing of known identities to which identified face regions detected within the acquired digital image data have been determined to correspond; and (c) a face recognition data component, comprising for an individual known identity: (i) an appearance table including one or more identity entries for the known identity; (ii) one or more identity tables corresponding to the one or more identity entries in the appearance table; and (iii) one or more face class tables corresponding to one or more face class entries of the one or more identity tables, wherein each face class table comprises one or more face print image entries corresponding to faceprints determined from normalized face regions identified within the acquired digital image, and (d) wherein the normalized face regions comprise spatially normalized face regions, which are normalized with respect to orientation or pose, or both, and wherein said normalized face regions are normalized with respect to a standard size based on one or more distances between eyes, nose, mouth, or one or more other facial features, or combinations thereof.
