Described embodiments utilize a multi-scale timeline approach in which photographs in a photograph album are organized into photograph clusters associated with multiple timeline scales. Each photograph cluster can be represented on a display screen as a thumbnail indicator in a photograph album window for efficient browsing. The thumbnail indicator can comprise one or more images automatically selected to represent a large number of photographs from the photograph cluster. Activation of one of the thumbnail indicators can trigger a change to another timeline scale. A multi-scale timeline one-step incremental spectral photograph clustering algorithm can also be utilized to quickly add or delete photographs from the cluster photographs at multiple timeline scales with a complexity approaching O(n). Near-duplicate photographs can also be automatically detected based on both time and visual features, and collapsed to a single representation to save space on the relatively small display screens typically included in mobile devices.
