Learning Situation Models for Providing Context- Aware Services (2008)
O. Brdiczka, J. L. Crowley, P. Reignier
In order to provide information and communication services without disrupting human activity, information services must implicitly conform to the current context of human activity. However, the...
Comparative study of People Detection in Surveillance Scenes (2008)
A. Negre, H. Tran, N. Gourier, D. Hall, A. Lux, J. L. Crowley
Abstract. We address the problem of determining if a given image region contains people or not, when environmental conditions such as viewpoint, illumination and distance of people from the camera...
INTRODUCTION LEARNING INDIVIDUAL ROLES FROM VIDEO IN A SMART HOME (2008)
O. Brdiczka, J. Maisonnasse, P. Reignier, J. L. Crowley
Abstract: This paper addresses learning and recognition of individual roles from video
Crowley, J. L., Brown, R. L., Gervais, F., Gibson, H. D.
Zircon and monazite from granitic sheets and dikes in the Monashee complex, Canadian Cordillera, were investigated to determine whether igneous crystallization occurred at 1·9 Ga or 50 Ma with 1·9...
View Invariant Object Recognition using Coloured Receptive Fields (2007)
. This paper describes a technique for the recognition and tracking of every day objects. The goal is to build a system in which ordinary desktop objects serve as physical icons in a vision based...

Multiple Resolution Representation and Probabilistic Matching of 2-D Gray-Scale Shape. (2002)
Crowley,J. L., Sanderson,A. C.
One approach to pattern classification is to match a structural description of a pattern to models which describe the structural properties of pattern classes. The central problem in structural...
This paper describes the results of experiments using an appearance manifold of a scene to estimate the position and orientation of a mobile robot. These experiments use principal components of...

Statistical Gesture Recognition through Modelling of Parameter Trajectories (1999)
J. Martin, D. Hall, J. L. Crowley
. The recognition of human gestures is a challenging problem that can contribute to a natural man--machine interface. In this paper, we present a new technique for gesture recognition. Gestures are...
A Prediction-Verification Strategy for Object Recognition using Local Appearance (1999)
This paper presents a technique for visual recognition in which physical objects are represented as families of surfaces in a local appearance space (typically 10 dimensions). The projection of the...
