Expanded model originally proposed by Schwartz and colleagues and adapted in our previous work [41] to describe the influence of scene segmentation cues on the tilt illusion in HCs. The proposed model accounts for perceived contrast in a range of laboratory and naturalistic stimuli, as well as the interaction of perceived contrast with higher-level scene segmentation cues such as directed spatial attention and object recognition. This model lets us characterize visual perceptual abnormalities in terms of specific alterations to local inhibitory responses and local and long-range excitatory response.
