Face Recognition Performance Using Additional Image Features
First Claim
1. A method of recognizing a face in an acquired digital image, comprising:
- receiving a first acquired image;
detecting, using a processor, a first face region within the first acquired image having a given size and a respective location within the first acquired image;
extracting first peripheral region data around the first face region;
displaying a first identifier with the first face region;
receiving a second acquired image that has a second face region;
extracting second peripheral region data around the second face region;
comparing the first peripheral region data and the second peripheral region data;
in response to determining that the first peripheral region data matches the second peripheral region data, displaying the same first identifier with the second face region.

Abstract
A technique is provided for recognizing faces in an image stream using a digital image acquisition device. A first acquired image is received from an image stream. A first face region is detected within the first acquired image having a given size and a respective location within the first acquired image. First faceprint data uniquely identifying the first face region are extracted along with first peripheral region data around the first face region. The first faceprint and peripheral region data are stored, and the first peripheral region data are associated with the first face region. The first face region is tracked until a face lock is lost. A second face region is detected within a second acquired image from the image stream. Second peripheral region data around the second face region are extracted. The second face region is identified upon matching the first and second peripheral region data.

15. A portable, digital image acquisition device, comprising a lens and image sensor for acquiring digital images, a processor, and a non-transitory processor-readable medium having code embedded therein for programming the processor to perform a method of recognizing a face in an acquired digital image, wherein the method comprises:
-
receiving a first acquired image; detecting, using a processor, a first face region within the first acquired image having a given size and a respective location within the first acquired image; extracting first peripheral region data around the first face region; displaying a first identifier with the first face region; receiving a second acquired image that has a second face region; extracting second peripheral region data around the second face region; comparing the first peripheral region data and the second peripheral region data; in response to determining that the first peripheral region data matches the second peripheral region data, displaying the same first identifier with the second face region. - View Dependent Claims (16, 17, 18, 19, 20, 21)
