TL;DR
The concept of perceptual image quality and its measurements are discussed and it is concluded that the effect of inter-subject differences is of less concern than the effects of different scenes.
Abstract
The concept of perceptual image quality and its measurements are discussed. A distinction is made between appreciation-oriented and performance-oriented quality. It is argued that in both cases psychometrical scaling is a very important method with respect to the measurement of perceptual quality and the strength of its dimensions and therefore is indispensable if one wants to relate these attributes to the physical image parameters. Scaled perceptual image quality and its validity are discussed in connection with physical image parameters such as size, gamma and spatial resolution. Scaled subjective impairments caused by quantisation errors are also dealt with. Finally, an example of scaled visual comfort and its relation with a few objective performance measures isgiven. It is concluded that the effectof inter-subject differences is of lessconcern than the effects of different scenes.

A photoelectric analog of the visual system is constructed in conformance with anatomical data, in the form of a color television camera chain feeding electrical signals to a “computer” (the brain).

It is demonstrated that the Hermite transform is in better agreement with human visual modeling than Gabor expansions, and therefore the scheme is presented as an analysis/resynthesis system.

The transfer function of the system responding to a 1° stimulus shows a band-pass filter type of processing for transients, confirming quantitatively earlier findings.

On the basis of some general system properties theoretical relationships have been established between parameters which characterise the sensitivity and inertia of the visual system in flicker and flash experiments.

65 Citations1989Joyce H. D. M. Westerink, J.A.J. Roufs
The results of the experiments show that the (angular) resolution expressed in periods per degree and the picture angle spanned by the display, each influence the quality independently, and subjective quality increases with resolution, but saturates at a resolution (6 dB cut-off frequency) of approximately 25 periods per degrees.
Spatial VisionAn object-oriented model for brightness perception
43 Citations1990Frans J.J. Blommaert, Jean-Bernard Martens
An object-oriented model for the brightness perception of static images is presented, showing how different aspects of brightness perception can be explained and unified within the model, at the expense of a less detailed description of psychophysical data.

Image quality as a general notion relales both to elementary an~ to complex visual funct_ions, and the appl~cability of notions on visual conspicuity and vasual search to amage quahty problems, and reading from alphanumeric displays are discussed.

27 Citations1981Frans J.J. Blommaert, Jacques A.J. Routs
A point spread function, chosen to link contrast sensitivity and stimulus dimensions, can be obtained from measured thresholds by assuming small-signal-linearity and peak detection for the visual system by taking specific measures against the effect of sensitivity drift.

15 Citations1989J.A.J. Roufs
Subjective quality was found to be optimal for non-linear luminance transfer and closely related to (subjective) brightness contrast, which is an important factor in perceptual image quality.
Signal ProcessingThe perceptual relevance of scale-space image coding
15 Citations1989J.-B. Martens, G.M.M. Majoor
It is shown in this paper that a one-to-one correspondence can be established between the different stages of the scale-space coder and a well-known model of the human visual system that is based on psychophysical data.
The effect of gamma on perceived image quality
10 Citations2003J.A.J. Roufs, I.M.J. Goossens
Although (subjected) sharpness is influenced by gamma, experiments show that no interaction is to be expected in the range of interest and the results show that luminance contrast ratio is an adequate measure of brightness contrast.
IEEE Transactions on CommunicationsApplication of scale space to image coding
10 Citations1990J.-B. Martens
It is shown that deriving a discrete formulation of scale space requires the solution to a more general problem; the optimum approximation of a signal by local patterns, which results in images that are noticeably unsharp.
