Anomaly Detection in Surveillance Videos
Proceedings of the ACM India Joint International Conference on Data Science and Management of Data, 2019Automated anomaly detection is a useful task that can aid investigations and detect crimes. To this end, we present a model that can be used as a tool for anomaly detection in surveillance videos. Following an unsupervised approach, we use an autoencoder model trained to minimize the reconstruction error between the input and the generated output.

Semantic video event search for surveillance video
2011 IEEE International Conference on Computer Vision Workshops (ICCV Workshops), 2011We present a distributed framework of understanding, indexing, and searching complex events from large amounts of surveillance video content. Video events and relationships between scene entities are represented by Spatio-Temporal And-Or Graphs (ST-AOG) and inferred in a distributed computing system using a bottom-up top-down strategy.

Privacy in video surveilled areas
Proceedings of the 2006 International Conference on Privacy, Security and Trust: Bridge the Gap Between PST Technologies and Business Services, 2006We present a system prototype for self-determination and privacy enhancement in video surveilled areas by integrating computer vision and cryptographic techniques into networked building automation systems. This paper describes research work that has been done within the first half of the collaborative blue-c-II project and is conducted by an ...

Middleware for video surveillance networks
Proceedings of the international workshop on Middleware for sensor networks, 2006Automated video surveillance networks are a class of sensor networks with the potential to enhance the protection of facilities such as airports and power stations from a wide range of threats. However, current systems are limited to networks of tens of cameras, not the thousands required to protect major facilities. Realising thousand camera automated

Time Scales in Video Surveillance
IEEE Transactions on Circuits and Systems for Video Technology, 2008Events in surveillance video occur over many time scales, but common approaches to background subtraction and video representation are implicitly based on a single temporal scale. In this work, we derive a set of causal filters which define a temporal scale-space representation for the activity at each pixel.

Path detection in video surveillance
Image and Vision Computing, 2002Abstract This paper addresses the problem of automatically extracting frequently used pedestrian pathways from video sequences of natural outdoor scenes. Path models are learnt from the accumulation of trajectory data over long time periods, and can be used to augment the classification of subsequent track data.

GIS-augmented video surveillance
International Journal of Geographical Information Science, 2010Registration in augmented reality is a process that merges virtual objects generated by a computer with real-world images captured by a camera. In this article, we present a method for registration of geospatial data applicable to outdoor video surveillance systems consisting of several PTZ cameras.
