How close are we to solving the problem of automated visual surveillance? A review of real-world surveillance, scientific progress and evaluative mechanisms

HM Dee, SA Velastin - Machine Vision and Applications, 2008 - Springer
The problem of automated visual surveillance has spawned a lively research area, with 2005
seeing three conferences or workshops and special issues of two major journals devoted …

[PDF][PDF] Detecting inexplicable behaviour.

HM Dee, DC Hogg - BMVC, 2004 - users.aber.ac.uk
This paper presents a novel approach to the detection of unusual or interesting events in
videos involving certain types of intentional behaviour, such as pedestrian scenes. The …

Face recognition using the POEM descriptor

NS Vu, HM Dee, A Caplier - Pattern Recognition, 2012 - Elsevier
Real-world face recognition systems require careful balancing of three concerns: computational
cost, robustness, and discriminative power. In this paper we describe a new descriptor, …

The perception and content of cast shadows: An interdisciplinary review

HM Dee, PE Santos - Spatial Cognition & Computation, 2011 - Taylor & Francis
Recently, psychologists have turned their attention to the study of cast shadows and demonstrated
that the human perceptual system values information from shadows very highly in the …

Leaf segmentation through the classification of edges

J Bell, HM Dee - arXiv preprint arXiv:1904.03124, 2019 - arxiv.org
We present an approach to leaf level segmentation of images of Arabidopsis thaliana plants
based upon detected edges. We introduce a novel approach to edge classification, which …

Crowd behaviour analysis using histograms of motion direction

HM Dee, A Caplier - 2010 IEEE International Conference on …, 2010 - ieeexplore.ieee.org
A practical system for the automated analysis of crowded scenes will have to deal with multiple
occlusions and tracking failures, in a context in which the cameras may move at any time …

Why are we still here? Experiences of successful women in computing

HM Dee, KE Petrie, RD Boyle, R Pau - ACM SIGCSE Bulletin, 2009 - dl.acm.org
This paper describes a study into the attitudes and experiences of women at three distinct
stages of the career pipeline: undergraduate, graduate student, and staff. Computing has often …

Qualitative robot localisation using information from cast shadows

P Santos, HM Dee, V Fenelon - 2009 IEEE International …, 2009 - ieeexplore.ieee.org
Recently, cognitive psychologists and others have turned their attention to the formerly neglected
study of shadows, and the information they purvey. These studies show that the human …

On the feasibility of using a cognitive model to filter surveillance data

HM Dee, DC Hogg - IEEE Conference on Advanced Video and …, 2005 - ieeexplore.ieee.org
This paper describes a novel approach to the problem of automated visual surveillance. The
authors have extended an existing algorithm which uses a cognitive model of navigation to …

Scene modelling and classification using learned spatial relations

HM Dee, DC Hogg, AG Cohn - … Conference, COSIT 2009 Aber Wrac'h …, 2009 - Springer
This paper describes a method for building visual scene models from video data using
quantized descriptions of motion. This method enables us to make meaningful statements about …
