Wavelet transform reassignment and the use of low-oscillation complex wavelets. (2006)
Journal Article
Addison, P., Morvidone, M., Watson, J. N., & Clifton, D. (2006). Wavelet transform reassignment and the use of low-oscillation complex wavelets. Mechanical Systems and Signal Processing, 20, 1429-1443. https://doi.org/10.1016/j.ymssp.2005.03.002

In this paper, we explore the use of new time-frequency reassignment tools for the enhancement of prominent features in the time-frequency plane of the wavelet transform. The reassignment method allows for the localisation of time-frequency and time-... Read More about Wavelet transform reassignment and the use of low-oscillation complex wavelets..

Wavelet analysis of the ECG: A review (2005)
Journal Article
Addison, P. (2005). Wavelet analysis of the ECG: A review. Physiological Measurement, 26(5), 155-199. https://doi.org/10.1088/0967-3334/26/5/R01

The wavelet transform has emerged over recent years as a powerful time–frequency analysis and signal coding tool favoured for the interrogation of complex nonstationary signals. Its application to biosignal processing has been at the forefront of the... Read More about Wavelet analysis of the ECG: A review.

Heart rate variability measurements and the prediction of ventricular arrhythmias. (2005)
Journal Article
Reed, M. J., Addison, P., & Robertson, C. E. (2005). Heart rate variability measurements and the prediction of ventricular arrhythmias. QJM: An International Journal of Medicine, 98, 87-95. https://doi.org/10.1093/qjmed/hci018

Heart rate variability (HRV) is the temporal variation between sequences of consecutive heartbeats. It is possible that HRV confers a survival advantage.In normal subjects, a variable heart rate is the normal physiological state. A loss of variabili...

Improved prediction of defibrillation success for out-of-hospital VF cardiac arrest using wavelet transform methods (2004)
Journal Article
Watson, J. N., Uchaipichata, N., Addison, P., Clegg, G. R., Robertson, C. E., Eftestol, T., & Steen, P. A. (2004). Improved prediction of defibrillation success for out-of-hospital VF cardiac arrest using wavelet transform methods. Resuscitation, 63(3), 2

We report an improved method for the estimation of shock outcome prediction based on novel wavelet transform-based time-frequency methods. Wavelet-based peak frequency, energy, mean frequency, spectral flatness and a new entropy measure were studied...
