Anomalous object detection by active search with PTZ cameras

作者:

Highlights:

• Pan-Tilt-Zoom cameras allow viewing larger scene instead of using several fixed ones.

• Automatically anomalous object detection is needed due to the large amount of videos.

• Objects which are in the scene are detected by using a deep neural networks.

• A Dirichlet-distribution algorithm determines which object is likely to be anomalous.

• Most likely to be anomalous object is automatically tracked by PTZ camera controller.
