iCap: New method for noise reduction in electroencephalography (EEG) signals

مجلة جامعة دمشق للعلوم الهندسية, 2022
Electroencephalographic (EEG) signal’s importance increases as the neurotechnology research and industry accelerate. Therefore, it is crucial to acquire noise-free signals by maximising the signal-to-noise ratio (SNR). Many methods are followed to clean

Attention-dependent modulation of cortical taste circuits revealed by granger causality with signal-dependent noise [PDF]

, 2013
We show, for the first time, that in cortical areas, for example the insular, orbitofrontal, and lateral prefrontal cortex, there is signal-dependent noise in the fMRI blood-oxygen level dependent (BOLD) time series, with the variance of the noise ...

Compression by Noise Equalization [PDF]

, 2013
For any relation of the noise variance with the gray value, a nonlinear transform h(g) can be applied so that the variance of the transformed signal h is constant.

Signal-to-noise Ratio measurements for Incilius luetkenii calls [PDF]

, 2016
Column A shows five transcripts described in the paper (1-5). Column B shows the number of speakers (1, 5, or 10 simulated toads). Column C shows distance between the loudspeakers and the microphone, in meters.

Signal-to-noise ratio analysis of single-pixel detection multiplexing under photon-noise. Cases of Hadamard and Cosine positive modulation [PDF]

, 2022
In typical single-pixel detection multiplexing, an unknown object is sequentially illuminated with intensity patterns: the total signal is summed into a single-pixel detector and is then demultiplexed to retrieve the object. Because of measurement noise,

Noise-Power Estimation Based on Ratio of Stationary Noise to Input Signal for Noise Reduction [PDF]

, 2014
This paper proposes a method for estimating noise-power spectrum and reducing stationary noise components in noisy speech signal. Noise reduction generally suppresses the stationary noise by applying a multiplicative gain calculated from the estimated ...
