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.
