Query-By-Example (QBE) retrieves shots which contain similar features (e.g., color, edge and motion) to those of example shots provided as a query. One crucial problem of OBE is the {\it diversity} of shots, where even for the same query, relevant shots contain significantly different features due to varied camera techniques. QBE approach is impractical if it requires the user to provide a large number of example shots in order to retrieve diverse relevant shots. Thus, we are developing Query-By-Virtual-Example (QBVE) approach which can efficiently create a large number of virtual example shots by synthesizing the user's gesture, 3D object and background image. In this paper, using large-scale video data, we examine the effectiveness of virtual example shots from the perspective of retrieval performance. In addition, we study about the importance of camera movements, the individual difference in users, and the synthesis strategy of gestures, 3D objects and backgrounds. |
