Face Recognition with Combined PCA-Based Datasets
First Claim
1. A face recognition method for working with two or more collections of facial images, comprising:
- (a) determining a representation framework for a first collection of facial images including at least principle component analysis (PCA) features;
(b) storing a representation of said first collection using said representation framework(c) determining a modified representation framework based on statistical properties of original facial image samples of a second collection of facial images and the stored representation of the first collection;
(d) combining the first and second collections without using original facial image samples;
(e) storing a representation of the combined image collection (super-collection) using said modified representation framework(f) comparing a representation of a current facial image, determined in terms of said modified representation framework, with one or more representations of facial images of the combined collection; and
(g) based on the comparing, determining whether one or more of the facial images within the combined collection matches the current facial image.

Abstract
A face recognition method for working with two or more collections of facial images is provided. A representation framework is determined for a first collection of facial images including at least principle component analysis (PCA) features. A representation of said first collection is stored using the representation framework. A modified representation framework is determined based on statistical properties of original facial image samples of a second collection of facial images and the stored representation of the first collection. The first and second collections are combined without using original facial image samples. A representation of the combined image collection (super-collection) is stored using the modified representation framework. A representation of a current facial image, determined in terms of the modified representation framework, is compared with one or more representations of facial images of the combined collection. Based on the comparing, it is determined which, if any, of the facial images within the combined collection matches the current facial image.

11. A face recognition method for working with two or more collections of facial images, comprising:
-
(a) determining different representation frameworks for first and second collections of facial images each including at least principle component analysis (PCA) features; (b) storing different representations of said first and second collections using said different representation frameworks; (c) determining a modified representation framework based on the different representations of the first and second collections, respectively; (d) combining the first and second collections without using original facial image samples; (e) storing a representation of the combined image collection (super-collection) using said modified representation framework (f) comparing a representation of a current facial image, determined in terms of said modified representation framework, with one or more representations of facial images of the combined collection; and (g) based on the comparing, determining whether one or more of the facial images within the combined collection matches the current facial image. - View Dependent Claims (12, 13, 14, 15, 16, 17)
