Multimedia Event Detection

Multimedia Event Detection

The Multimedia Event Detection (MED) evaluation track is part of the TRECVid Evaluation. The goal of MED is to assemble core detection technologies into a system that can search multimedia recordings for user-defined events based on pre-computed metadata. The metadata stores developed by the systems are expected to be sufficiently general to permit re-use for subsequent user defined events.

In 2012 and 2013, Multimedia Event Recounting (MER) was evaluated separately. Thereafter, it was combined into the MED evaluations.

MED17 is the eighth MED evaluation and features 10 new events and a new search collection.
