“Optimized Self-Localization for SLAM in Dynamic Scenes using Probability Hypothesis Density Filters”

Open Access: IEEE Transactions on Signal Processing Authors:  Christine Evers and Patrick A. Naylor Abstract:  In many applications, sensors that map the positions of objects in unknown environments are installed on dynamic platforms. As measurements are relative to the observer's sensors, scene mapping requires accurate knowledge of the observer state. However, in practice, observer reports...

“Direction of Arrival Estimation in the Spherical Harmonic Domain Using Subspace Pseudointensity Vectors”

IEEE Xplore: IEEE/ACM Transactions on Audio, Speech, and Language Processing Authors: Alastair H. Moore, Christine Evers, and Patrick A. Naylor Abstract: Direction of arrival (DOA) estimation is a fundamental problem in acoustic signal processing. It is used in a diverse range of applications, including spatial filtering, speech dereverberation, source separation and diarization. Intensity vector-based DOA...

“Multichannel online blind speech dereverberation with marginalization of static observation parameters in a Rao-Blackwellized particle filter,”

SpringerLink Access: in Journal of Signal Processing Systems, vol. 63, no. 3, pp. 315–332, 2011 Authors: C. Evers and J. R. Hopgood Abstract: Room reverberation leads to reduced intelligibility of audio signals and spectral coloration of audio signals. Enhancement of acoustic signals is thus crucial for high-quality audio and scene analysis applications. Multiple sensors can be...

“Parametric modelling for single-channel blind dereverberation of speech from a moving speaker“

IEEEXplore Access: in IET Signal Processing, vol. 2, no. 2, pp. 59–74, June, 2008 Authors: C. Evers and J. R. Hopgood Abstract: Single-channel blind dereverberation for the enhancement of speech acquired in acoustic environments is essential in applications where microphone arrays prove impractical. In many scenarios, the source-sensor geometry is not varying rapidly, but in...

“Bayesian single channel blind speech dereverberation using Monte Carlo methods”

Scitation Access: in The Journal of the Acoustical Society of America, vol. 123, no. 5, pp. 3586–3586, 2007 Authors: J. R. Hopgood, C. Evers , and J. Bell Abstract: Audio signals in confined spaces exhibit reverberation due to reflections off surrounding obstacles. Moreover, the signal is distorted by noise, usually modeled as an additive signal...
