A method of identifying a particular person in a digital image collection,
wherein at least one of the images in the digital image collection
contains more than one person, includes providing at least one first
label for a first image in the digital image collection containing a
particular person and at least one other person; wherein the first label
identifies the particular person and a second label for a second image in
the digital image collection that identifies the particular person; using
the first and second labels to identify the particular person;
determining features related to the particular person from the first
image or second image or both; and using such particular features to
identify another image in the digital image collection believed to
contain the particular person.
