Lightness constancy: ratio invariance and luminance profile [PDF]

open access: yes, 2009
The term simultaneous lightness constancy describes the capacity of the visual system to perceive equal reflecting surfaces as having the same lightness despite lying in different illumination fields.

Gaze-contingent flicker pupil perimetry detects scotomas in patients with cerebral visual impairments or glaucoma [PDF]

open access: yes, 2018
The pupillary light reflex is weaker for stimuli presented inside as compared to outside absolute scotomas. Pupillograph perimetry could thus be an objective measure of impaired visual processing.

Assessing visual acuity in visual prostheses through a virtual-reality system [PDF]

open access: yesarXiv, 2022
Current visual implants still provide very low resolution and limited field of view, thus limiting visual acuity in implanted patients. Developments of new strategies of artificial vision simulation systems by harnessing new advancements in technologies are of upmost priorities for the development of new visual devices.

Attention modulates spatial priority maps in the human occipital, parietal and frontal cortices. [PDF]

open access: yes, 2013
Computational theories propose that attention modulates the topographical landscape of spatial 'priority' maps in regions of the visual cortex so that the location of an important object is associated with higher activation levels.

Multi-field visualization [PDF]

open access: yes, 2011
Modern science utilizes advanced measurement and simulation techniques to analyze phenomena from fields such as medicine, physics, or mechanics. The data produced by application of these techniques takes the form of multi-dimensional functions or fields, which have to be processed in order to provide meaningful parts of the data to domain experts ...

Visual ChatGPT: Talking, Drawing and Editing with Visual Foundation Models [PDF]

open access: yesarXiv, 2023
ChatGPT is attracting a cross-field interest as it provides a language interface with remarkable conversational competency and reasoning capabilities across many domains. However, since ChatGPT is trained with languages, it is currently not capable of processing or generating images from the visual world.

The Computational Magic of the Ventral Stream: Towards a Theory [PDF]

open access: yes, 2011
I conjecture that the sample complexity of object recognition is mostly due to geometric image transformations and that a main goal of the ventral stream – V1, V2, V4 and IT – is to learn-and-discount image transformations.
