Signal to noise ratio analysis in virtual source array imaging [PDF]
, 2013 We consider correlation-based imaging of a reflector located on one side of a passive array where the medium is homogeneous. On the other side of the array the illumination by remote impulsive sources goes through a strongly scattering medium.

Signal-to-noise Ratio measurements for Incilius luetkenii calls
, 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.

The Area Signal-to-Noise Ratio: A Robust Alternative to Peak-Based SNR in Spectroscopic Analysis
In spectroscopic analysis, the peak-based signal-to-noise ratio (pSNR) is commonly used but suffers from limitations such as sensitivity to noise spikes and reduced effectiveness for broader peaks. We introduce the area-based signal-to-noise ratio (aSNR) as a robust alternative that integrates the signal over a defined region of interest, reducing ...

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 ...

ROBUST IMAGE TRANSMISSION USING SPIHT AND TURBO- CODES
Electrica, 2008 This work describes a method for providing robustness to errors from a binary symmetric channel for the SPIHT image compression. The source rate and channel rate are jointly optimized by a stream of fixed-size channel packets.

Unbiased Injection of Signal-Dependent Noise in Variance-Stabilized Range
, 2016 <p>The design, optimization, and validation of many image processing or image-based analysis systems often requires testing of the system performance over a dataset of images corrupted by noise at different signal-to-noise ratio regimes.

METHOD FOR MEASURING PEAK SIGNAL TO NOISE RATIO BASED FRAME WEIGHT ON DYNAMIC IMAGE
, 2014 동적 영상의 프레임 가중치 기반 영상 피크 신호 대 잡음비 측정 방법이 개시된다. 멀티미디어 영상의 품질을 평가하는 항목으로 피크 신호 대 잡음비(peak signal to noise ratio)를 측정하는 방법은, 송신단에서 송신하는 원본 영상과 상기 원본 영상을 수신하는 수신단의 수신 영상을 비교하여 초기 피크 신호 대 잡음비를 계산하는 단계; 및 상기 수신 영상의 각 프레임에 대하여 손실된 패킷에 따른 가중치(weight)를 이용하여 상기 초기
