Region based anomaly detection with real-time training and analysis.

Adey, P. and Bordewich, M. and Breckon, T.P. and Hamilton, O.K. (2019) 'Region based anomaly detection with real-time training and analysis.', in 2019 18th IEEE International Conference On Machine Learning And Applications (ICMLA), Boca Raton, FL, USA, 2019. Piscataway, NJ: IEEE, pp. 495-499.

Abstract

We present a method of anomaly detection that is capable of real-time operation on a live stream of images. The real-time performance applies to the training of the algorithm as well as subsequent analysis, and is achieved by substituting the region proposal mechanism used in [9] with one that makes the overall method more efficient. where they generate thousands of regions per image, we generate far fewer but better targeted regions. We also propose a 'convolutional' variant which does away with region extraction altogether, and propose improvements to the density estimation phase used in both variants.
