The Effect of Contrast Randomisation on the Discrimination of Changes in the Slopes of the Amplitude Spectra of Natural Scenes
TLDR
The results imply that the observers do not usually detect changes in contrast in just one narrow spatial-frequency band when they discriminate changes in the slope of the amplitude spectrum, and for edge-enhanced (whitened) pictures, there is some evidence to suggest that observers rely on contrast changes in only a limited low-spatial- frequencies band.
Discrimination of Changes in the Slopes of the Amplitude Spectra of Natural Images: Band-Limited Contrast and Psychometric Functions
TLDR
The forms of the psychometric functions for the discrimination task were entirely compatible with the hypothesis that the task relies upon the ability to discriminate changes of contrast.
Discrimination of amplitude spectrum slope in the fovea and parafovea and the local amplitude distributions of natural scene imagery.
TLDR
A local amplitude distribution analysis with a large set of high-resolution natural scene imagery is conducted and it is found that the results of that analysis provided a better account of the alpha discrimination thresholds for stimuli presented to the fovea as opposed to the parafovea.
The magnitude of center-surround facilitation in the discrimination of amplitude spectrum is dependent on the amplitude of the surround.
TLDR
The results suggest that the visual system is sensitive to contextual interactions for stimuli that have the characteristics of natural images.

Detection of changes in the amplitude spectra of natural images is explained by a band-limited local-contrast model
TLDR
A model that explains the variety of threshold magnitudes is described, and the success of this band-limited contrast model is shown further in experiments where the slopes of the amplitude spectra of the stimuli are changed within restricted frequency bands.

TLDR
A definition of local band-limited contrast in images is proposed that assigns a contrast value to every point in the image as a function of the spatial frequency band and is helpful in understanding the effects of image-processing algorithms on the perceived contrast.
Human discrimination of fractal images.
TLDR
This paper investigates the question of which value of the exponent beta describes the power spectrum of the ensemble of images to which the visual system is optimally tuned, and results are consistent with, but do not provide direct evidence for, the theory that thevisual system is tuned to an ensemble of image with Markov statistics.
What Does the Retina Know about Natural Scenes?
TLDR
It is argued that the retinal goal is to transform the visual input as much as possible into a statistically independent basis as the first step in creating a redundancy reduced representation in the cortex, as suggested by Barlow.
Comparison of contrast-normalization and threshold models of the responses of simple cells in cat striate cortex.
TLDR
The two main models of the output nonlinearity of spatiotemporal summation in simple cells of the cat's visual cortex are fitted rigorously to a variety of previously published neurophysiological data, in order to determine whether one model is a better explanation of the data.

TLDR
The results obtained with six natural images suggest that the orientation and the spatial-frequency tuning of mammalian simple cells are well suited for coding the information in such images if the goal of the code is to convert higher-order redundancy into first- order redundancy.
Contrast masking in human vision.
TLDR
A masking model is presented that encompasses contrast detection, discrimination, and masking phenomena that includes a linear spatial frequency filter, a nonlinear transducer, and a process of spatial pooling that acts at low contrasts only.

TLDR
It is suggested that the spatial parameters of the cortical 'filters' (e.g., bandwidths of simple and complex cells) are closely related to these higher-order statistics that bear important relations to visual coding.
