Signal-to-Noise Ratio Estimation in Passive Correlation-Based Imaging [PDF]
SIAM Journal on Imaging Sciences, 2013 We consider imaging with passive arrays of sensors using as illumination ambient noise sources. The first step for imaging under such circumstances is the computation of the cross correlations of the recorded signals, which have attracted a lot of attention recently because of their numerous applications in seismic imaging, volcano monitoring, and ...

Signal-to-noise ratio of Gaussian-state ghost imaging [PDF]
Physical Review A, 2009 The signal-to-noise ratios (SNRs) of three Gaussian-state ghost imaging configurations--distinguished by the nature of their light sources--are derived. Two use classical-state light, specifically a joint signal-reference field state that has either the maximum phase-insensitive or the maximum phase-sensitive cross correlation consistent with having a ...

Measuring the signal-to-noise ratio in magnetic resonance imaging: a caveat
Signal Processing, 2004 The validity of the signal-to-noise ratio (SNR) as an objective quality measure for biomedical images has been the subject of a long-standing debate. Nevertheless, the SNR is the most popularly used measure both for assessing the quality of images and for evaluating the effectiveness of image enhancement and signal processing techniques.

Signal-to-noise ratio and signal-to-noise efficiency in SMASH imaging [PDF]
Magnetic Resonance in Medicine, 1999 A general theory of signal-to-noise ratio (SNR) in simultaneous acquisition of spatial harmonics (SMASH) imaging is presented, and the predictions of the theory are verified in imaging experiments and in numerical simulations. In a SMASH image, multiple lines of k-space are generated simultaneously through combinations of magnetic resonance signals in ...
