TLDR
Evidence is presented of evidence which suggests that the sensitivity of frequency-tuned filters in the visual system is matched to this image statistic, so that, on average, different channels respond with equal activity to natural scenes.
The contribution of psychophysical spatial frequency channels to the discrimination of broadband contrast.
The design and function of the human visual system is thought to have been shaped by the environment and tasks humans have performed throughout evolution and experience. Thus, it is important to…

Sensitivity to the slope of the amplitude spectrum is dependent on the spectral slopes of recently viewed environments: A visual adaptation study in modified reality
Scenes contain many statistical regularities that could benefit visual processing if accounted for by the visual system. One such statistic is the orientation-averaged slope (α) of the amplitude…

TLDR
This paper reviews some of the statistical properties of natural scenes that allow the visual code to be efficient and argues that such wavelet codes are efficient because they increase the independence of the vectors' outputs by finding the sparse structure available in the input.
Can the theory of “whitening” explain the center-surround properties of retinal ganglion cell receptive fields?
Local Contrast in Natural Images: Normalisation and Coding Efficiency
TLDR
Responsibility variability, both within and between scenes, is reduced by normalisation, and the entropy of the response distribution is increased afternormalisation, indicating a more efficient transfer of information.
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.
Influence of scale and orientation on the visual perception of natural scenes
It is well known that the distribution of spatial content with respect to spatial scale in real-world scenes falls in accordance with a 1/ f α relation. Equally well known is the tendency for an…

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.
Band-limited contrast in natural images explains the detectability of changes in the amplitude spectra
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.

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.
Origins of scaling in natural images
TLDR
This work proposes that the salient universal structure present in natural images is their composition of independent occluding objects, and shows that a power-law distribution of apparent object sizes combined with strongly correlated intra-object structure gives rise to the ubiquitous power- Law spectrum in natural scenes.
Statistics of Natural Images: Scaling in the Woods
TLDR
This work gathers images from the woods and finds that these scenes possess an ensemble scale invariance, and this non-Gaussian character cannot be removed through local linear filtering, meaning information is maximized at fixed channel variance.
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.
