Simultaneous place and object recognition using collaborative context information

In this paper, we present a practical place and object recognition method for guiding visitors in building environments. Due to motion blur or camera noise, places or objects can be ambiguous. The first key contribution of this work is the modeling of bidirectional interaction between places and objects for simultaneous reinforcement. The second key contribution is the unification of visual context, including scene context, object context, and temporal context. The last key contribution is a practical demonstration of the proposed system for visitors in a large scale building environment.
