Tutorial on How to Ask Queries
The VTT queries can be image-based or scene-based in a storyline. The system integrates information from multiple cameras over time to answer queries about the scene and events.
Define Objects of Interest
Tab: Add Objects
- - Specify an object of interest by drawing a bounding box or a point.
- - Give it a name so that you can ask queries about it later.
In this example, we draw an bounding box around a person and name it John.
Compose Queries
Tab: Query
A query consists one or more attribute and/or relationship predicates.
