A method of identifying at least one particular person of interest in a
collection of digital images taken over time, includes providing the
collection of digital images with each digital image containing one or
more persons; storing in a digital database an appearance model having a
set of features that are distance measurements associated with facial
features of the particular person of interest at an associated time; and
providing an individual recognition classifier that uses the appearance
model and the associated time to identify the particular person of
interest in images from the collection of digital images.
