Compression of multiple user photo galleries

摘要

The possibility of sharing multimedia contents in easy and ubiquitous way has brought to the creation of multiuser photo albums. Pictures and video sequences taken by different people attending common social events (e.g., concerts and sport competitions) are gathered together into huge sets of heterogeneous multimedia data. These databases require effective compression strategies that exploit the common visual information related to the scene but compensate effectively the differences depending on the acquiring viewpoints, camera models, and acquisition time instants.
