Nonparametric Bayesian attentive video analysis
2008
Pattern Recognition (ICPR), Proceedings of the International Conference on
Preserved Fulltext
We address the problem of object-based visual attention from a Bayesian standpoint. ...
To this end we propose a framework relying on nonparametric Bayesian techniques, namely variational inference on a mixture of Dirichlet processes. ...
In this respect, variational techniques have proven to be a viable tool for video analysis. ...

Introducing a novel way to compute rare motion patterns, we estimate latent factors of foreground motion patterns through Bayesian Nonparametric Factor analysis. ...
We demonstrate the system on a public video data set, showing key aspects of the browsing paradigm. ...
Since the number of latent factors is unknown in advance, we employ recent advances in Bayesian nonparametric factor analysis. ...

This paper explores the use of a Bayesian non-parametric topic modeling technique for the purpose of anomaly detection in video data. We present results from two experiments. ...
In the second dataset, consisting of video data from a static seafloor camera capturing images of a busy coral reef, the proposed technique was able to detect all three instances of an underwater vehicle ...
The Bayesian nonparametric nature of the approach insures that the anomaly models adapts automatically to the data, without requiring careful tuning of the hyper-parameters. ...
