VIVIE: A video-surveillance indexer via identity extraction

VIVIE is a system for video sequence indexing. Video frames are annotated according to the identities of appearing subjects. Different interacting modules perform different processing steps, and each can be possibly substituted with a different one performing the same task using a different method. Classification and clustering are the most challenging activities. Differently from most existing similar systems, VIVIE accounts for the concomitant appearance of two identities in the same clip, and exploits such information for identity mapping. VIVIE was tested on 7 video clips and on a subset of the SCFace database to assess its performances.
