Several theoretical models for the prediction of liminal contrast are studied. One model that employs the known excitation and inhibition spread functions of the eye accurately predicts, at 10 mL, thresholds for circular targets, sine waves, and rectangles, including the line as a special case.

Lightweight Salient Object Detection via Hierarchical Visual Perception Learning
IEEE Transactions on Cybernetics, 2020Recently, salient object detection (SOD) has witnessed vast progress with the rapid development of convolutional neural networks (CNNs). However, the improvement of SOD accuracy comes with the increase in network depth and width, resulting in large ...

An adult with the diagnosis of cortical blindness, complaining of a complete visual loss of 2 years in duration, was found to have a small preserved visual field and remarkably preserved visual abilities. Although denying visual perception, he correctly named objects, colors, and famous faces, recognized facial emotions, and read various types of ...

Underwater Image Enhancement via Weighted Wavelet Visual Perception Fusion
IEEE transactions on circuits and systems for video technology (Print)Underwater images typically suffer from various quality degradation issues due to the scattering and absorption of light, but these degraded-quality underwater images are unbeneficial for analysis and applications.

Effects of Language on Visual Perception
Trends in Cognitive Sciences, 2020Does language change what we perceive? Does speaking different languages cause us to perceive things differently? We review the behavioral and electrophysiological evidence for the influence of language on perception, with an emphasis on the visual ...

Systematization of Corner Cases for Visual Perception in Automated Driving
2020 IEEE Intelligent Vehicles Symposium (IV), 2020One major task in automated driving is the development of robust and safe visual perception modules. It is of utmost importance that visual perception reacts adequately to so-called corner cases, which range from overexposure of the image sensor to ...

Visual perception — A hypothesis
Medical Hypotheses, 1991Based on the results of after-image experiments, it can be concluded that the retinal perception of image position is linked to head position information, since this affects after-image positioning. Why actual perception of object position is not affected is hypothesised as a resetting of the retinal horizon, from information received on head position.

Visual Perception and Xerography
Science, 1968An electrostatic copying machine was used to model the perception of simultaneous brightness contrast. Such a model may assist the study of sensory inhibition by permitting the study of complex situations as they are transformed by rules similar to those at work in neural integration.
