Perception-memory interactions reveal a computational strategy for perceptual constancy

Maria Olkkonen, Toni P. Saarela, Sarah R. Allred
2016 Journal of Vision  
The reflectance model, finally, captures the memory-context interaction better than the contrast model, both qualitatively and quantitatively.  ...  Observers compared the lightness of two stimuli under a memory demand (a delay between the stimuli), a context change (different surround luminance), or both.  ...  Here we take advantage of the fact that contrast and reflectance models generate different predictions about the interaction between perceptual and memory effects.  ...

A Neurodynamical Model of Brightness Induction in V1

Olivier Penacchio, Xavier Otazu, Laura Dempere-Marco, Maurice Ptito
2013 PLoS ONE  
This work suggests that intra-cortical interactions in V1 could, at least partially, explain brightness induction effects and reveals how a common general architecture may account for several different  ...  The proposed computational model successfully accounts for well known psychophysical effects for static contexts and also for brightness induction in dynamic contexts defined by modulating the luminance  ...  maintained in working memory [51] .  ...

Perceptually-driven decision theory for interactive realistic rendering

Reynald Dumont, Fabio Pellacini, James A. Ferwerda
2003 ACM Transactions on Graphics  
In this paper we introduce a new approach to realistic rendering at interactive rates on commodity graphics hardware.  ...  We demonstrate the usefulness of this approach for various applications such as diffuse texture caching, environment map prioritization and radiosity mesh simplification.  ...  This work has been realized using equipment generously donated by Intel Corporation and nVidia Corporation.  ...

Contextual Effects in Face Lightness Perception Are Not Expertise-Dependent

Dorita Chang, Yin Cheang, May So
2018 Vision  
We instead speculate that such influences manifest in terms of an interaction between race assumptions (e.g., expected surface reflectance patterns) and traditional mechanisms for reflectance computations  ...  We suggest that contextual influences in lightness perception are unlikely to be guided by classical mechanisms that drive face perception.  ...  Acknowledgments: We thank the Chinese National Hi-Tech Program and ISVISION Tech. Co. Ltd. for granting permission to use face images from the CAS-PEAL-R1 database.  ...
