Image classification using compression distance (2008)

E. Trucco, M. Chantler (editors, Yuxuan Lan, Richard Harvey

The normalised compression distance measures the mutual compressibility of two signals. We show that this distance can be used for classification on real images. Furthermore, the same compressor can...

Towards texture classification in real scenes (2008)

Paul Southam, Richard Harvey

Two new texture features, based on morphological scale-space processors are introduced. The new methods are shown to have good performance over a variety of tests. We demonstrate that if texture...

Evaluating a colour morphological scale-space (2008)

Stuart Gibson, J. Andrew Bangham, Richard Harvey

Scale-spaces are usually associated with the diffusion equation operating on greyscale images. This paper presents a scale-space that is based on graph morphology and works in colour. The system is...

Investigation between the S377G3 GATA-4 polymorphism and migraine (2008)

Chikhani, Sherin, Fernandez, Francesca, Karl, Poetter, Brendan, Toohey, Harvey, Richard, Griffiths, Lyn

Migraine is a common and painful neurological disorder, with genetic and environmental components. Several conditions have been shown to be comorbid with migraine, notably a cardiac malformation...

TLM for vision systems (2007)

Richard Harvey

Anisotropic diffusion is an increasingly important technique in primary vision systems. It requires the solution of a nonlinear diffusion equation. The transmission line matrix (TLM) technique is...

The art of scale-space (2003)

J. Andrew Bangham, Stuart Gibson, Richard Harvey

Artists pictures rarely have photo-realistic detail. Tools to create pictures from digital photographs might, therefore, include methods for removing detail. These tools such as Gaussian and...

Relationship between body mass and gastro-oesophageal reflux symptoms: The Bristol Helicobacter Project (2003)

Murray, Liam, Johnston, Brian, Lane, Athene, Harvey, Ian, Donovan, Jenny, Nair, Prakash, ...

Objective To examine the relationship between body mass and gastro-oesophageal reflux in a large population-representative sample from the UK. Design and setting Cross-sectional population-based...

Extraction of Visual Features for Lipreading (2002)

Iain Matthews, Tim Cootes, J. Andrew Bangham, Stephen Cox, Richard Harvey

The multi-modal nature of speech is often ignored in human-computer interaction but lip deformation, and other body such as head and arm motion all convey additional infor-mation. We integrate speech...

Extraction of Visual Features for Lipreading (2002)

Iain Matthews, Timothy F. Cootes, J. Andrew Bangham, Stephen Cox, Richard Harvey

Abstract—The multimodal nature of speech is often ignored in human-computer interaction, but lip deformations and other body motion, such as those of the head, convey additional information. We...

Recognition and retrieval via histogram trees (2001)

Stuart Gibson, Richard Harvey

This paper explores a new method for analysing and comparing image histograms. The technique amounts to a novel way of backprojecting an image into one with fewer, statistically significant colours....

Building systems to block pornography (1999)

Yi Chan, Richard Harvey, Dan Smith

Experience and recent lawsuits have led large internet users to search for ways to filter email and web traffic by content. This paper reviews the prospects for this research for specific domain:...

Scale-space trees and applications as filters for stereo vision and image retrieval (1999)

J. Andrew Bangham, Kimberly Moravec, Richard Harvey, Mark Fisher

Images are re-mapped as scale-space trees. The minimal data structure is then augmented by “complement nodes ” to increase the practical value of the representation. It is then shown how the...

The segmentation of images via scale-space trees (1998)

J. Andrew Bangham, Javier Ruiz Hidalgo, Richard Harvey, Gavin Cawley

A useful representation of an image would be an object tree in which nodes represent objects, or parts of objects, and which includes at least one node that, together with its children, represents...

Lipreading Using Shape, Shading and Scale (1998)

Iain Matthews, Tim Cootes, Stephen Cox, Richard Harvey, J. Andrew Bangham

This paper compares three methods of lipreading for visual and audio-visual speech recognition. Lip shape information is obtained using an Active Shape Model (ASM) lip tracker but is not as effective...

A Comparison of Active Shape Model and Scale Decomposition Based Features for Visual Speech Recognition (1998)

Iain Matthews, J. Andrew Bangham, Richard Harvey, Stephen Cox

Two quite different strategies for characterising mouth shapes for visual speech recognition (lipreading) are compared. The first strategy extracts the parameters required to fit an active shape...

Improving Stereo Performance in Regions of Low Texture (1998)

Kimberly Moravec Richard, Richard Harvey, J. Andrew Bangham

In images with low texture the performance of conventional dense stereo can be poor. The usual solution to this is to use a large window but this itself can be problematic as the large window can...

Lip Reading From Scale-Space Measurements (1997)

Richard Harvey Iain, Richard Harvey, Iain Matthews, J. Andrew Bangham, Stephen Cox

Systems that attempt to recover the spoken word from image sequences usually require complicated models of the mouth and its motions. Here we describe a new approach based on a fast mathematical...

The Robustness of Some Scale-Spaces (1997)

Richard Harvey, Alison Bosson, J. Andrew Bangham

There are several methods for forming a scale-space and they may be classified as being based on diffusion or morphology. However it is rare for the methods to be compared. Here we outline a method...
