Free Energy Adjusted Peak Signal to Noise Ratio (FEA-PSNR) for Image Quality Assessment
Peak signal to noise ratio (PSNR), the de facto universal image quality metric has been widely criticized as having poor correlation with human subjective quality ratings. In this paper, it will be illustrated that the low performance of PSNR as an image quality metric is partially due to its inability of differentiating image contents.

Peak signal-to-noise ratio revisited: Is simple beautiful?
2012 Fourth International Workshop on Quality of Multimedia Experience, 2012Heavy criticism has been directed against using peak signal-to-noise ratio (PSNR) as a full reference quality metric for digitally processed images and video, since many studies have shown a weak correlation between subjective quality scores and the respective PSNR values.

NRPSNR: No-Reference Peak Signal-to-Noise Ratio for JPEG2000
2013 Data Compression Conference, 2013The aim of this work is to define a no-referenced perceptual image quality estimator applying the perceptual concepts of the Chromatic Induction Model. The approach consists in comparing the received image, presumably degraded, against the perceptual versions (different distances) of this image degraded by means of a Model of Chromatic Induction, which

Smoothing and the signal-to-noise ratio of peaks in electron spectroscopy
Journal of Electron Spectroscopy and Related Phenomena, 1989Abstract The smoothing of noisy peaks in electron Spectroscopy by convolutional algorithms is studied further to provide clear guidelines with which the analyst may obtain a rapid optimum result. Following detailed earlier work by Seah, Dench, Gale and Groves we focus on the Savizky and Golay cubic/quadratic, quartic/quintic and Gaussian ...

Quantification of the accuracy limits of image registration using peak signal-to-noise ratio
Radiological Physics and Technology, 2016A new method was developed for quantifying the accuracy limits of image registration devices and the distortion of anatomical structures in verification images without image registration. A correlation was found between peak signal-to-noise ratio (PSNR) and the amount of parallel movement (1-10 mm at 1-mm intervals) of a rectangular parallelepiped ...

Improvement of the signal-to-noise ratio of chromatographic peaks by Fourier transform
Analytica Chimica Acta, 1991Abstract A method is described for digital smoothing of chromatographic signals by using Fourier transform and is compared with some earlier methods. A new procedure is reported for determining the correct value of the cutoff frequency; a smoothing window is described which distorts the frequency function only slightly at low frequencies but smooths ...
