Face Recognition Training Method and Apparatus
First Claim
1. Within a processor-based, digital image acquisition device, a method of face recognition within an acquired digital image, comprising:
- acquiring with a digital image acquisition device a digital image of a scene that includes a partial face image from a sequential stream of multiple images;
within the digital image acquisition device, automatically cropping the partial face image or removing one or more non-facial items from the digital image, or both, and thereby generating a more full-size partial face image; and
applying face recognition by comparing the more full-size partial face image to one or more images stored within a face image library.

Abstract
A device is trained for face recognition. A first acquired digital image of a scene includes a face. Face image data is extracted and stored in a face image library along with an unique identifier. A second acquired digital image may or may not include the face of the same person as the face in the first acquired digital image. Face recognition is applied to extracted face data of the second digital image, and the face of the first digital image is displayed as a match to the face of the second digital image when the first and second images are determined to match or the second digital image or a face therein is identified with biometric data stored along with the first digital image when the faces in the first and second images are determined to match.

12. One or more non-transitory processor-readable media encoded with processor-readable code for programming a processor that is built into a portable device configured for acquiring digital images to perform a method of face recognition within a digital image, wherein the method comprises:
-
acquiring with the portable device a digital image of a scene that includes a partial face image from a sequential stream of multiple images; automatically cropping the partial face image or removing one or more non-facial items from the digital image, or both, and thereby generating a more full-size partial face image; and applying face recognition by comparing the more full-size partial face image to one or more images stored within a face image library. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
