Visual illusions via neural dynamics: Wilson–Cowan-type models and the efficient representation principle
We reproduce suprathreshold perception phenomena, specifically visual illusions, by Wilson–
Cowan (WC)-type models of neuronal dynamics. Our findings show that the ability to …

Cortical-inspired Wilson–Cowan-type equations for orientation-dependent contrast perception modelling
We consider the evolution model proposed in Bertalmío (Front Comput Neurosci 8: 71,
2014), Bertalmío et al.(IEEE Trans Image Process 16 (4): 1058–1072, 2007) to describe …

A neural field model for color perception unifying assimilation and contrast
A Song, O Faugeras, R Veltz - PLoS computational biology, 2019 - journals.plos.org
We address the question of color-space interactions in the brain, by proposing a neural field
model of color perception with spatial context for the visual area V1 of the cortex. Our …
