The vireo group participated in four tasks: instance search, semantic indexing, multimedia event detection and known-item search. In this paper,we will present our approaches and discuss the evaluation results. Instance Search (INS): We experimented four runs to contrast the following for instance search: full matching (vireo b) versus partial matching (vireo m); use of weak geometric information (vireo b) versus stronger spatial configuration (vireo s); use of face matching (vireo f).
