A method includes accessing a digital image including a plurality of faces including a first face and a second face. The method includes identifying a plurality of identification regions of the digital image including a first identification region associated with the first face and a second identification region associated with the second face. The method also includes assigning the digital image to a first face cluster of a plurality of face clusters when a difference between data descriptive of the first identification region and data descriptive of a face cluster identification region of the first face cluster satisfies a threshold. The method further includes assigning the digital image to a second face cluster of the plurality of face clusters based at least partially on a frequency of the second face and the first face appearing together in an image.
