1. A method, comprising:
- detecting in an input image a face region containing at least a portion of a person'"'"'s face;
identifying in the input image an auxiliary identification region outside the face region;
determining facial features characterizing the face region;
calculating auxiliary identification features characterizing the auxiliary identification region;
deriving an indexing datum from the facial features and the auxiliary identification features; and
storing the indexing datum in association with the input image;
wherein the detecting, the identifying, the determining, the calculating, the deriving, and the storing are performed by computing hardware.

Abstract
Method, apparatus, and systems for extracting features from face regions and auxiliary identification regions of images are described. In one aspect, a face region containing at least a portion of a person'"'"'s face is detected in an input image. An auxiliary identification region outside the face region is identified in the input image. Facial features characterizing the face region are determined. Auxiliary identification features characterizing the auxiliary identification region are calculated. An indexing datum is derived from the facial features and the auxiliary identification features. The indexing datum is stored in association with the input image.
