Abstract
Face detection is performed on a plurality of images to identify a plurality of faces. A subset of the plurality of faces is activated, including by loading into memory the subset of faces and/or data corresponding to the subset of faces. At least one of the plurality of faces is left un-activated. A distance for each pair of activated faces is calculated, wherein the distance is associated with a measure of a similarity between a first face and a second face. The activated faces are clustered into a plurality of groups based at least in part on the distances. A representative face is selected from each group resulting from the clustering and the representative faces are displayed.
