No-Reference Quality Assessment of Authentically Distorted Images Based on Local and Global Features

open access: yesJournal of Imaging, 2022
With the development of digital imaging techniques, image quality assessment methods are receiving more attention in the literature. Since distortion-free versions of camera images in many practical, everyday applications are not available, the need for ...

Luminance contrast provides metric depth information

open access: yesRoyal Society Open Science, 2023
The perception of depth from retinal images depends on information from multiple visual cues. One potential depth cue is the statistical relationship between luminance and distance; darker points in a local region of an image tend to be farther away than

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.

Explaining Orientation Adaptation in V1 by Updating the State of a Spatial Model

open access: yesFrontiers in Computational Neuroscience, 2022
In this work, we extend an influential statistical model based on the spatial classical receptive field (CRF) and non-classical receptive field (nCRF) interactions (Coen-Cagli et al., 2012) to explain the typical orientation adaptation effects observed ...

Viewing Art in Different Contexts

open access: yesFrontiers in Psychology, 2020
While aesthetic experiences are not limited to any particular context, their sensorial, cognitive and behavioral properties can be profoundly affected by the circumstances in which they occur.

No-Reference Image Quality Assessment with Global Statistical Features

open access: yesJournal of Imaging, 2021
The perceptual quality of digital images is often deteriorated during storage, compression, and transmission. The most reliable way of assessing image quality is to ask people to provide their opinions on a number of test images.

Visual Discomfort and Variations in Chromaticity in Art and Nature

open access: yesFrontiers in Neuroscience, 2021
Visual discomfort is related to the statistical regularity of visual images. The contribution of luminance contrast to visual discomfort is well understood and can be framed in terms of a theory of efficient coding of natural stimuli, and linked to ...

Human Texture Vision as Multi-Order Spectral Analysis

open access: yesFrontiers in Computational Neuroscience, 2021
Texture information plays a critical role in the rapid perception of scenes, objects, and materials. Here, we propose a novel model in which visual texture perception is essentially determined by the 1st-order (2D-luminance) and 2nd-order (4D-energy ...

Rat sensitivity to multipoint statistics is predicted by efficient coding of natural scenes

open access: yeseLife, 2021
Efficient processing of sensory data requires adapting the neuronal encoding strategy to the statistics of natural stimuli. Previously, in Hermundstad et al., 2014, we showed that local multipoint correlation patterns that are most variable in natural ...

An image reconstruction framework for characterizing initial visual encoding

open access: yeseLife, 2022
We developed an image-computable observer model of the initial visual encoding that operates on natural image input, based on the framework of Bayesian image reconstruction from the excitations of the retinal cone mosaic.
