Gesture recognition for augmentative human computer interaction
(IEEE, 1995)Augmentative and alternative communication has always suffered from difficulties of equipment set-up and interaction. A three-dimensional input device is presented which is based on a non-contact movement sensor. In this ... -
Assessing motility through abdominal sound monitoring
(IEEE, 1997)This paper presents the results of an investigation into a computerised system for the assessment of gastrointestinal motility through the recording and analysis of bowel sounds. The system described is aimed primarily at ... -
An uncoupled oscillator model of the Hoffmann reflex
(IEEE, 1998)A simple, new, mathematical model for the Hoffmann reflex is outlined. This model has been developed by considering phase synchronisation of the underlying neuromuscular processes by the electrical stimulation pulse. The ... -
Hybrid multiplier/CORDIC unit for online handwriting recognition
(IEEE, 1999)Traditionally online handwriting recognition (OHR) implementations use general-purpose processor architectures. The pre-processing step of OHR comprises regular array-based tasks such as normalisation, feature extraction ... -
Exaction of the optic disk boundary in digital fundus images
(IEEE, 1999)The methods of active contours (?snakes?) and level sets were applied to images of the retina in order to locate the outer boundary of the optic disk. A gradient-vector-flow based active contour was used as it performed ... -
Classification of the electrocardiogram using selected wavelet coefficients and linear discriminants
(IEEE, 2000)Twenty-live wavelet coefficients were selected as inputs and cross-validation used to estimate the classifier performance. An overall accuracy of 72.3% was achieved using a database of 500 ECG records independently classified ... -
Color video segmentation using level sets
(IEEE, 2000)A novel segmentation algorithm for color video sequences using the level set technique is proposed. This algorithm is applied to the problem of automatic face region segmentation in video sequences. Given a target color ... -
Beat classification for use in arrhythmia analysis
(IEEE, 2000)An important step in the classification of arrhythmias is beat classification. The aim of this work is to classify the beats in the MIT-BIH Arrhythmia database and to investigate pertinent features for beat classification. ... -
A comparison of the ECG classification performance of different feature sets
(IEEE, 2000)This study investigates the automatic classification of the Frank lead ECG into different disease categories. A comparison of the performance of a number of different feature sets is presented. The feature sets considered ... -
Quantitative analysis and comparison of diffusion tensor imaging tractography algorithms
(2006)This paper describes a platform developed for analysis of diffusion tensor image data using different tractography algorithms. The platform allows these algorithms to be compared both quantitatively and qualitatively. Two ... -
Tracing individual public transport customers from an anonymous transaction database
(University of South Florida, National Center for Transit Research, 2006)Data mining concepts are used frequently throughout the transportation research sector. This paper uses the concept of the market basket technique on public transport users as a means of gaining more insight into their ... -
Automatic classification of shoeprints for use in forensic science based on the fourier transform
(IEEE, 2003)This study developed a system of automatic classification of shoeprint images into groups belonging to the same sole pattern. When presented with an image of a new shoeprint the system displays a ranked sequence ... -
EEG alpha power and coherence time courses in a sustained attention task
(IEEE, 2003)Alpha activity at certain brain regions and the functional relationships between these regions quantified by alpha coherence were examined in a fixed sequence Sustained Attention to Response Task (SART), which involves the ... -
Automatic classification of ECG beats using waveform shape and heart beat interval features
(IEEE, 2003)The paper presents the classification performance of an automatic classifier of the electrocardiogram (ECG) for the detection of normal, premature ventricular contraction and fusion beat types. Both linear discriminants ... -
A simultaneous filtering and feature extraction strategy for direct brain interfacing
(IEEE, 2002)Parametric modeling strategies are explored in conjunction with Linear Discriminant Analysis (LDA) to facilitate an Electroencephalogram (EEG) based direct-brain interface. A left/right self-paced typing exercise is analysed ... -
Fast marching methods applied to face location in videophone applications using colour information
(IEEE, 2002)A new method is proposed to automatically segment out a person's face from a given sequence of images that consists of a head-and-shoulder view, using the fast marching level set approach. The method proposed involves a ... -
Automatic sleep apnoea detection using measures of amplitude and heart rate variability from the electrocardiogram
(IEEE, 2002)A method for the automatic processing of the electrocardiogram (ECG) for the detection of disordered breathing associated with obstructive sleep apnoea is presented. The method provides a minute-by-minute analysis of ... -
