Natural image statistics for mouse vision. [PDF]

open access: yesPLoS ONE, 2022
The mouse has dichromatic color vision based on two different types of opsins: short (S)- and middle (M)-wavelength-sensitive opsins with peak sensitivity to ultraviolet (UV; 360 nm) and green light (508 nm), respectively.

Neuronal variability reflects probabilistic inference tuned to natural image statistics [PDF]

open access: yesNature Communications, 2021
The neural sampling theory suggests that neuronal variability encodes the uncertainty of probabilistic inferences. This paper shows that response variability in primary visual cortex reflects the statistical structure of visual inputs, as required for ...

Gaussian-binary restricted Boltzmann machines for modeling natural image statistics. [PDF]

open access: yesPLoS ONE, 2017
We present a theoretical analysis of Gaussian-binary restricted Boltzmann machines (GRBMs) from the perspective of density models. The key aspect of this analysis is to show that GRBMs can be formulated as a constrained mixture of Gaussians, which gives ...

Discriminating natural image statistics from neuronal population codes. [PDF]

open access: yesPLoS ONE, 2010
The power law provides an efficient description of amplitude spectra of natural scenes. Psychophysical studies have shown that the forms of the amplitude spectra are clearly related to human visual performance, indicating that the statistical parameters ...

Contextual interactions in grating plaid configurations are explained by natural image statistics and neural modeling [PDF]

open access: yesFrontiers in Systems Neuroscience, 2016
Processing natural scenes requires the visual system to integrate local features into global object descriptions. To achieve coherent representations, the human brain uses statistical dependencies to guide weighting of local feature conjunctions ...

Predicting cortical dark/bright asymmetries from natural image statistics and early visual transforms. [PDF]

open access: yesPLoS Computational Biology, 2015
The nervous system has evolved in an environment with structure and predictability. One of the ubiquitous principles of sensory systems is the creation of circuits that capitalize on this predictability.

Relating natural image statistics to patterns of response covariability in macaque primary visual cortex [PDF]

open access: yesNature Communications
Determining how the brain encodes sensory information requires understanding the structure of cortical activity, including how its variability is shared among neurons. The role of this covariability in cortical representations of natural visual inputs is

Thermal Image Restoration Based on LWIR Sensor Statistics

open access: yesSensors, 2021
An imaging system has natural statistics that reflect its intrinsic characteristics. For example, the gradient histogram of a visible light image generally obeys a heavy-tailed distribution, and its restoration considers natural statistics.

Analysis and Synthesis of Natural Texture Perception From Visual Evoked Potentials

open access: yesFrontiers in Neuroscience, 2021
The primate visual system analyzes statistical information in natural images and uses it for the immediate perception of scenes, objects, and surface materials.
