Effect of signal-to-noise ratio on the measurement of individual T1 values from superimposed peaks

Journal of Magnetic Resonance (1969), 1991
Abstract Spectra of complex organic molecules or biological macromolecules often contain peaks which are severely overlapped or superimposed. It is not readily apparent to what extent relaxation data for individual peak components may be extracted. In this paper, one- and two-component analyses of simulated relaxation data are carried out in order to

Enhancement of Raman Spectra Obtained at Low Signal-To-Noise Ratios: Matched Filtering and Adaptive Peak Detection

Applied Spectroscopy, 1985
Two methods of Raman spectral peak enhancement are described. The matched-filter approach employs an optimal filter to maximize the signal-to-noise ratio at its output. The impulse response of the matched filter is the reversed version of the profile of the spectral peak to be enhanced; therefore, the effectiveness of the matched filter depends on a ...

Estimation of the peak signal-to-noise ratio for compressed video based on generalized Gaussian modeling

Optical Engineering, 2007
The peak signal-to-noise ratio (PSNR) is one of the most popular video quality metrics. This ratio is computed using both original and processed images. We propose a new method to estimate the PSNR from an encoded bit stream without using original video sequences.

No-reference peak signal to noise ratio estimation based on generalized Gaussian modeling of transform coefficient distributions

Optical Engineering, 2012
We present a no-reference peak signal to noise ratio (PSNR) estimation algorithm based on discrete cosine transform (DCT) coefficient distributions from H.264/MPEG-4 part 10 advanced video codec (H.264/AVC) bitstreams. To estimate the PSNR of a compressed picture without the original picture on the decoder side, it is important to model the ...
