1. A method of face categorization and annotation of a face image library, comprising:
- acquiring with a digital image acquisition device a digital image of a scene that includes a face;
acquiring a series of relatively low resolution reference images captured around the time of capture of said digital image;
extracting candidate face regions from successive frames of said reference images;
maintaining information from the successive frames of said reference images, including location data and a cumulative confidence level that the candidate face regions extracted from said successive frame of said series of reference images comprise said face, and based on the information from the series of reference images, determining that said face is present within said digital image;
automatically cropping the face or removing one or more non-facial items from the digital image, or both, and thereby generating a full-size face image; and
storing the full-size face image with other indicia identifying a person corresponding to the face in a face image library.

Abstract
A method of face categorization and annotation of a face image library includes automatically cropping a face within an acquired digital image or removing one or more non-facial items from the digital image, or both, and thereby generating a full-size face image. The full-size face image is stored with other indicia identifying a person corresponding to the face in a face image library of an embedded device such as a mobile camera phone or other handheld camera device.

16. One or more non-transitory computer readable media encoded with a computer program for programming one or more processors to perform a method of face categorization and annotation of a face image library, the method comprising:
-
acquiring with a digital image acquisition device a digital image of a scene that includes a face; acquiring a series of relatively low resolution reference images captured around the time of capture of said digital image; extracting candidate face regions from successive frames of said reference images; maintaining information from the successive frames of the reference images, including location data and a cumulative confidence level that the candidate face regions extracted from said successive frame of said series of reference images comprise said face, and based on the information from the series of reference images, determining that said face is present within said digital image; automatically cropping the face or removing one or more non-facial items from the digital image, or both, and thereby generating a full-size face image; and storing the full-size face image with other indicia identifying a person corresponding to the face in a face image library. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
