Is it Interesting?: Comparing human and machine judgements on the PETS dataset

Hogg, David C.; Dee, Hannah (2004)
Detecting inexplicable behaviour

Hogg, David C.; Dee, Hannah (2004)
Improving ICP with Easy Implementation for Free Form Surface Matching

Liu, Yonghuai (2004-02)

Automatic range image registration and matching is an attractive but unresolved problem in both the machine vision and pattern recognition literature. Since automatic range image registration and matching is inherently a ...
A volumetric approach to risk assessment in mammography: a feasibility study

Blot, L.; Zwiggelaar, Reyer (2005)

In mammography, the reliable estimation of the volume of glandular tissue can lead to improvements in mean glandular dose calculations and mammographic risk assessment. Using the hint model, this paper presents a novel ...
An estimation of firmness for solid ellipsoidal fruits

Ouyang, F.; Blot, L.; Zwiggelaar, Reyer; Cherng, A. -. P. (2005)

This paper deals with a non-destructive firmness estimation method using vibrational characteristics for solid fruits of oblate ellipsoidal shape. In association with the previous work, a general estimation formula is ...
On the feasibility of using a cognitive model to filter surveillance data

Dee, Hannah; Hogg, David C. (2005)
Eliminating False Matches for the Projective Registration of Free-Form Surfaces with Small Translational Motions

Liu, Yonghuai (2005-05)

In this paper, we make a detailed study of two rigid-motion constraints. The importance of these two constraints is twofold: first, they reveal the inherent relationship between the three-dimensional-two-dimensional (3-D-2-D) ...
Automatic 3d free form shape matching using the graduated assignment algorithm.

Liu, Yonghuai (2005-10)

Three-dimensional free form shape matching is a fundamental problem in both the machine vision and pattern recognition literatures. However, the automatic approach to 3D free form shape matching still remains open. In this ...
Computer technology in detection and staging of prostate carcinoma: a review

Williams, S.; Zhu, Y.; Zwiggelaar, Reyer (2006)

After two decades of increasing interest and research activity, computer-assisted diagnostic approaches are reaching the stage where more routine deployment in clinical practice is becoming a possibility [Kruppinski, E.A., ...
Navigational strategies and surveillance

Hogg, David C.; Dee, Hannah (2006)

This paper will describe new work that attempts to perform the modelling of human behaviour not at the level of visible patterns of motion, but at the level of intentions. By inferring intentions in terms of known goals, ...
A hybrid ASM approach for sparse volumetric data segmentation

Zhu, Y.; Zwiggelaar, Reyer; Williams, S. (2007)

Three-Dimensional (3D) Active Shape Modeling (ASM) is a straightforward extension of 2D ASM. 3D ASM is robust when true volumetric data is considered. However, when the information in one dimension is sparse, pure 3D ASM ...
Visual Segmentation-Based Data Record Extraction From Web Documents

Weatherston, M.; Obregon, A.; Li, Longzhuang; Liu, Yonghuai (2007-08-13)

Semi-structured data records contained in the Web pages provide useful information for shopping agents and metasearch engines. In this paper, we present a visual segmentation-based data record extraction (VSDR) method to ...
Accurate Range Image Registration: Eliminating or Modelling Outliers

Li, Longzhuang; Liu, Honghai; Wei, Baogang; Liu, Yonghuai (2007-09)

Automatic and accurate range image registration is often a prerequisite step for range image analysis and interpretation. Due to occlusion, appearance and disappearance of points in different images, outliers inevitably ...
The evaluation of effects on breast cancer diagnoses using the mammographic semantic information

Qi, Da; Denton, Erika R. E.; Leason, Joanna M. E.; Othman, Diaa; Zwiggelaar, Reyer (2008)

In this paper, we describe the evaluation of the effects of mammographic semantic information in breast cancer diagnoses. A brief description of relations between semantic information and image features are given. We ...
Analysis of using anatomical linear structure information in mammographic risk assessment

Zwiggelaar, R. (Springer-Verlag, Berlin, 2008)
Mammographic Segmentation Based on Texture Modelling of Tabár Mammographic Building Blocks

He, W.; Zwiggelaar, R.; Denton, E. R. E.; Muhimmah, I. (2008)

We present an approach to automate texton selection to achieve optimized mammogram segmentation results with respect to mammographic building blocks (i.e. nodular, linear, homogeneous, and radiolucent) as described by ...
Mammographic risk assessment: does anatomical linear structure information improve the accuracy of a density-based classifier?

Zwiggelaar, R. (2008)

Mammographic risk assessment is concerned with the probability of a woman developing breast cancer. Recently, it has been suggested that the density of linear structures is related to risk. Two independent sets of mammographic ...
Modelling scenes using the activity within them

Dee, Hannah; Fraile, Roberto; Hogg, David C.; Cohn, Anthony G. (2008)

This paper describes a method for building visual “maps” from video data using quantized descriptions of motion. This enables unsupervised classification of scene regions based upon the motion patterns observed within them. ...
Eigendetection of masses considering false positive reduction and breast density information

Zwiggelaar, R. (2008)

The purpose of this article is to present a novel algorithm for the detection of masses in mammographic computer-aided diagnosis systems. Four key points provide the novelty of our approach: (1) the use of eigenanalysis ...
Notes on a qualitative theory of shadows
