Rapid classification of surface reflectance from image velocities
We propose a method for rapidly classifying surface reflectance directly from the output of spatio-temporal filters applied to an image sequence of rotating objects. Using image data from only a single frame, we compute ...
Rapid inference of object rigidity and reflectance using optic flow
Rigidity and reflectance are key object properties, important in their own rights, and they are key properties that stratify motion reconstruction algorithms. However, the inference of rigidity and reflectance are both ...
Color vision in humans and computers
Humans and many other species rely on color for object recognition. What are the biological underpinnings of color vision and how can we computationally model human color perception? In this study we briefly summarize ...
Border ownership selectivity in human early visual cortex and its modulation by attention
(Society for Neuroscience, 2009)
Natural images are usually cluttered because objects occlude one another. A critical aspect of recognizing these visual objects is to identify the borders between image regions that belong to different objects. However, ...
The role of sense of coherence and physical activity in positive and negative affect of Turkish adolescents
(Libra Publishers, Inc., 2009)
This study investigated the role of sense of coherence and total physical activity in positive and negative affect. Participants were 376 (169 female, 206 male, and 1 missing value) student volunteers from different ...
Top-down attentional modulation of spatial frequency processing in scene perception
Recent evidence suggests that spatial frequency (SF) processing of simple and complex visual patterns is flexible. The use of spatial scale in scene perception seems to be influenced by people's expectations. However as ...
What can we learn from toddlers about categorical perception of color? comments on Goldstein, Davidoff, and Roberson
(Elsevier Inc., 2009)
We comment on Goldstein, Davidoff, and Roberson's replication and extension (Journal of Experimental Child Psychology, 102, 219-238 ) of our study of the effect of toddlers' color term knowledge on their categorical ...
Retinotopic sensitisation to spatial scale: evidence for flexible spatial frequency processing in scene perception
(Elsevier Ltd., 2006)
Observers can use spatial scale information flexibly depending on categorisation task and on their prior sensitisation. Here, we explore whether attentional modulation of spatial frequency processing at early stages of ...
Market entry decisions: effects of absolute and relative confidence
(Hogrefe Publishing, 2008)
In a market entry game, the number of entrants usually approaches game-theoretic equilibrium quickly, but in real-world markets business start-ups typically exceed market capacity, resulting in chronically high failure ...
