Material—illumination ambiguities and the perception of solid objects

SC Pont, SF Te Pas - Perception, 2006 - journals.sagepub.com
The appearance of objects depends on their material, shape, and on the illumination
conditions. Conversely, object appearance provides us with cues about the illumination and the …

[PDF][PDF] The influence of eccentricity on the indication of the singular point in rotating flow fields

SF Te Pas, AML Kappers, JJ Koenderink… - Studies in Ecological …, 1996 - Citeseer
We investigate how weil subjects can indicate the singular point (the point with zero speed)
in a rotating flow field, and whether performance depends on eccentricity. Our stimuli consist …

Numerosity perception is tuned to salient environmental features

PA Grasso, G Anobile, R Arrighi, DC Burr, GM Cicchini - IScience, 2022 - cell.com
Numerosity perception is a key ability to guide behavior. However, current models propose
that number units encode an abstract representation of numerosity regardless of the non-…

Perception of illumination direction in images of 3-D convex objects: Influence of surface materials and light fields

BG Khang, JJ Koenderink, AML Kappers - Perception, 2006 - journals.sagepub.com
We investigated the perception of illumination direction in images of 3-D convex objects
under variations of light field and surface material properties. In a first experiment, we used an …

Shape from shading from images rendered with various surface types and light fields

BG Khang, JJ Koenderink, AML Kappers - Perception, 2007 - journals.sagepub.com
Shape constancy is referred to as the tendency for the perceived shape of an object to remain
unchanged even under changed viewing and illumination conditions. We investigated, in …

[PDF][PDF] Differences between haptic and visual judgements of curvature

AML Kappers, JJ Koenderink… - Studies in Ecological …, 1996 - Citeseer
Large systematic scale differences show up when subjects are asked to match the curvature
of a haptically presented surface with a visually presented cross-section. Scaling factors …

Serial dependence in time and numerosity perception is dimension-specific

I Togoli, M Fedele, M Fornaciai, D Bueti - Journal of Vision, 2021 - jov.arvojournals.org
The perception of a visual event (eg, a flock of birds) at the present moment can be biased
by a previous perceptual experience (eg, the perception of an earlier flock). Serial …
