Autor: Jonathan P. May, Eno Hysi, Shyh-Dar Li, Lauren A. Wirtzfeld, Elijus Undzys, Michael C. Kolios

Publikováno v: Photoacoustics
Photoacoustics, Vol 5, Iss C, Pp 25-35 (2017)

Frequency analysis of the photoacoustic radiofrequency signals and oxygen saturation estimates were used to monitor the in-vivo response of a novel, thermosensitive liposome treatment. The liposome encapsulated doxorubicin (HaT-DOX) releasing it rapi

Insights into photoacoustic speckle and applications in tumor characterization

Autor: Jason Zalev, Michael C. Kolios, Eno Hysi, Muhannad N. Fadhel, Eric M. Strohm, Michael J. Moore

Publikováno v: Photoacoustics, Vol 14, Iss, Pp 37-48 (2019)

In ultrasound imaging, fully-developed speckle arises from the spatiotemporal superposition of pressure waves backscattered by randomly distributed scatterers. Speckle appearance is affected by the imaging system characteristics (lateral and axial re

An integrated MVDR beamformer for speech enhancement using a local microphone array and external microphones

Autor: Randall Ali, Toon van Waterschoot, Marc Moonen

Publikováno v: EURASIP Journal on Audio, Speech, and Music Processing, Vol 2021, Iss 1, Pp 1-20 (2021)

An integrated version of the minimum variance distortionless response (MVDR) beamformer for speech enhancement using a microphone array has been recently developed, which merges the benefits of imposing constraints defined from both a relative transf

Over the recent years, machine learning techniques have been employed to produce state-of-the-art results in several audio related tasks. The success of these approaches has been largely due to access to large amounts of open-source datasets and enha

Sparse pursuit and dictionary learning for blind source separation in polyphonic music recordings

Autor: Sören Schulze, Emily J. King

Publikováno v: EURASIP Journal on Audio, Speech, and Music Processing, Vol 2021, Iss 1, Pp 1-25 (2021)

We propose an algorithm for the blind separation of single-channel audio signals. It is based on a parametric model that describes the spectral properties of the sounds of musical instruments independently of pitch. We develop a novel sparse pursuit

Forward-backward recursive expectation-maximization for concurrent speaker tracking

EURASIP Journal on Audio, Speech, and Music Processing

In this paper, a study addressing the task of tracking multiple concurrent speakers in reverberant conditions is presented. Since both past and future observations can contribute to the current location estimate, we propose a forward-backward approac

Instrumental playing techniques such as vibratos, glissandos, and trills often denote musical expressivity, both in classical and folk contexts. However, most existing approaches to music similarity retrieval fail to describe timbre beyond the so-cal

Dynamic out-of-vocabulary word registration to language model for speech recognition

Autor: Bohan Chen, Norihide Kitaoka, Yuya Obashi

Publikováno v: EURASIP Journal on Audio, Speech, and Music Processing, Vol 2021, Iss 1, Pp 1-8 (2021)

We propose a method of dynamically registering out-of-vocabulary (OOV) words by assigning the pronunciations of these words to pre-inserted OOV tokens, editing the pronunciations of the tokens. To do this, we add OOV tokens to an additional, partial

Binaural speaker identification using the equalization-cancelation technique

Autor: Sina Ghalamiosgouei, Masoud Geravanchizadeh

Publikováno v: EURASIP Journal on Audio, Speech, and Music Processing, Vol 2020, Iss 1, Pp 1-15 (2020)

In real applications, environmental effects such as additive noise and room reverberation lead to a mismatch between training and testing signals that substantially reduces the performance of far-field speaker identification. As a solution to this mi
