Succesful participation of CERTH-ITI in interactive known-item video search of TRECVID 2012

CERTH-ITI participated to the Known-Item Search (KIS) Task of TRECVID 2012 with the interactive video retrieval engine VERGE. VERGE results achieved the second place, among the submissions made by all institutions participating to TRECVID 2012 KIS task (19 runs from 5 different institutions) with interactive systems. The latest version of VERGE supports advanced retrieval functionalities including visual similarity search, visual concept-based retrieval, video similarity based on PLSA and full text search, as well as two different representations (i.e. shot and video based). More information about VERGE is available here. Feel free to try on line the latest version of VERGE and search in the TRECVID 2012 KIS test data collection.
