Abstract

A method of improving recognition of a particular person in images by constructing a composite model of at least the portion of the head of that particular person, includes acquiring a collection of images taken during a particular event; identifying image(s) having a particular person in the collection; identifying one or more features in the identified image(s) associated with that particular person; searching the collection using the identified features to identify the particular person in other images of the collection; and constructing a composite model of at least a portion of the particular person'"'"'s head using identified images of the particular person.

Claims

1. A method of improving recognition of a particular person in images by constructing a composite model of at least the portion of the head of that particular person, comprising

(a) acquiring a collection of images taken during a particular event;

(b) identifying image(s) having a particular person in the collection;

(c) identifying one or more features in the identified image(s) associated with that particular person;

(d) searching the collection using the identified features to identify the particular person in other images of the collection; and

(e) constructing a composite model of at least a portion of the particular person'"'"'s head using identified images of the particular person.

2. The method of claim 1 wherein the features include apparel.

3. The method of claim 1 wherein the composite model includes:

(i) stored portions of the head of the particular person for later searching;

(ii) determining the pose of the head in each of the identified images having the particular person;

or

(iii) creating a three dimensional model of the head of the particular person;

4. The method of claim 3 further including storing the identified features for use in searching subsequent collections.

5. The method of claim 3 further comprising using the composite model (i) or (iii) to search other image collections to identify the particular person.

6. The method of claim 5 further including using the stored identified features to search other image collections to identify the particular person.

7. The method of claim 3 further comprising using the composite model (ii) and extracting head features and using such extracted head features to search other image collections to identify the particular person.

8. The method of claim 7 further including using the stored identified features to search other image collections to identify the particular person.
