Subspace discovery for video anomaly detection

, 2010
PhDIn automated video surveillance anomaly detection is a challenging task. We address this task as a novelty detection problem where pattern description is limited and labelling information is available only for a small sample of normal instances.

Face detection and clustering for video indexing applications [PDF]

, 2003
This paper describes a method for automatically detecting human faces in generic video sequences. We employ an iterative algorithm in order to give a confidence measure for the presence or absence of faces within video shots.

MAC-REALM: A video content feature extraction and modelling framework [PDF]

, 2013
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.A consequence of the ‘data deluge’ is the exponential increase in digital video footage, while the ability to find relevant video clips diminishes ...

STV-based Video Feature Processing for Action Recognition

, 2012
In comparison to still image-based processes, video features can provide rich and intuitive information about dynamic events occurred over a period of time, such as human actions, crowd behaviours, and other subject pattern changes.

Semi-supervised Learning for Anomalous Trajectory Detection [PDF]

, 2008
A novel learning framework is proposed for anomalous behaviour detection in a video surveillance scenario, so that a classifier which distinguishes between normal and anomalous behaviour patterns can be incrementally trained with the assistance of a ...

Binary histogram based split/merge object detection using FPGAs [PDF]

, 2010
Tracking of objects using colour histograms has proven successful in various visual surveillance systems. Such systems rely heavily on similarity matrices to compare the appearance of targets in successive frames.

Activity-driven content adaptation for effective video summarisation

, 2010
In this paper, we present a novel method for content adaptation and video summarization fully implemented in compressed-domain. Firstly, summarization of generic videos is modeled as the process of extracted human objects under various activities/events.

Detecting complex events in user-generated video using concept classifiers [PDF]

, 2012
Automatic detection of complex events in user-generated videos (UGV) is a challenging task due to its new characteristics differing from broadcast video.
