Novel bias-reduced coherence measure for EEG-based speech tracking in listeners with hearing impairment

Autor: Oskar Keding, Emina Alickovic, Martin A. Skoglund, Maria Sandsten

Publikováno v: Frontiers in Neuroscience, Vol 18 (2024)

In the literature, auditory attention is explored through neural speech tracking, primarily entailing modeling and analyzing electroencephalography (EEG) responses to natural speech via linear filtering. Our study takes a novel approach, introducing

Time-frequency feature extraction for classification of episodic memory

Autor: Rachele Anderson, Maria Sandsten

Publikováno v: EURASIP Journal on Advances in Signal Processing, Vol 2020, Iss 1, Pp 1-18 (2020)

Abstract This paper investigates the extraction of time-frequency (TF) features for classification of electroencephalography (EEG) signals and episodic memory. We propose a model based on the definition of locally stationary processes (LSPs), estimat

Performance Comparison of Time-Frequency Distributions for Estimation of Instantaneous Frequency of Heart Rate Variability Signals

Autor: Nabeel Ali Khan, Peter Jönsson, Maria Sandsten

Publikováno v: Applied Sciences, Vol 7, Iss 3, p 221 (2017)

The instantaneous frequency (IF) of a non-stationary signal is usually estimated from a time-frequency distribution (TFD). The IF of heart rate variability (HRV) is an important parameter because the power in a frequency band around the IF can be use

Scaled reassigned spectrograms applied to linear transducer signals

Autor: Josefin, Starkhammar, Isabella, Reinhold, Tobias, Erlöv, Maria, Sandsten

Publikováno v: JASA express letters. 1(5)

This study evaluates the applicability of scaled reassigned spectrograms (ReSTS) on ultrasound radio frequency data obtained with a clinical linear array ultrasound transducer. The ReSTS's ability to resolve axially closely spaced objects in a phanto
