We describe a novel architecture for semantic image retrieval---in particular, retrieval of instances of visual situations.

Fast On-Line Kernel Density Estimation for Active Object Localization

no code implementations • 16 Nov 2016 • Anthony D. Rhodes, Max H. Quinn, Melanie Mitchell

In our system, prior situation knowledge is captured by a set of flexible, kernel-based density estimations---a situation model---that represent the expected spatial structure of the given situation.

Active Object Localization in Visual Situations

no code implementations • 2 Jul 2016 • Max H. Quinn, Anthony D. Rhodes, Melanie Mitchell

We compare the results with several baselines and variations on our method, and demonstrate the strong benefit of using situation knowledge and active context-driven localization.
