The lawful imprecision of human surface tilt estimation in natural scenes

open access: yeseLife, 2018
Estimating local surface orientation (slant and tilt) is fundamental to recovering the three-dimensional structure of the environment. It is unknown how well humans perform this task in natural scenes.

Fixations on objects in natural scenes: dissociating importance from salience

open access: yesFrontiers in Psychology, 2013
The relation of selective attention to understanding of natural scenes has been subject to intense behavioral research and computational modeling, and gaze is often used as a proxy for such attention.

Gravitational effects of scene information in object localization

open access: yesScientific Reports, 2021
We effortlessly interact with objects in our environment, but how do we know where something is? An object’s apparent position does not simply correspond to its retinotopic location but is influenced by its surrounding context. In the natural environment,

Variance predicts salience in central sensory processing

open access: yeseLife, 2014
Information processing in the sensory periphery is shaped by natural stimulus statistics. In the periphery, a transmission bottleneck constrains performance; thus efficient coding implies that natural signal components with a predictably wider range ...

A photo‐based quality assessment model for the estimation of PM2.5 concentrations

open access: yesIET Image Processing, 2022
Rapid economic growth has caused severe environmental pollution, which has aroused great concern. This pollution affects public health and impairs visibility, therefore, it should be given greater consideration.

Statistics of High-level Scene Context

open access: yesFrontiers in Psychology, 2013
Context is critical to our ability to recognize environments and to search for objects within them: contextual associations have been shown to modulate reaction time and object recognition accuracy, as well as influence the distribution of eye movements ...

Progress in Blind Image Quality Assessment: A Brief Review

open access: yesMathematics, 2023
As a fundamental research problem, blind image quality assessment (BIQA) has attracted increasing interest in recent years. Although great progress has been made, BIQA still remains a challenge.

A dynamic scale-mixture model of motion in natural scenes

open access: yeseLife
Some of the most important tasks of visual and motor systems involve estimating the motion of objects and tracking them over time. Such systems evolved to meet the behavioral needs of the organism in its natural environment and may therefore be adapted ...
