Three Perceptual Dimensions for Specular and Diffuse Reflection

Matteo Toscani, Dar'ya Guarnera, Giuseppe Claudio Guarnera, Jon Yngve Hardeberg, Karl R. Gegenfurtner
2020 ACM Transactions on Applied Perception  
Apart from color, most of these models separate reflectance into diffuse (following Lambert's law [56] ) and specular dimensions and have parameters controlling the their angular distributions [14, 29,  ...  Specifically, "Lightness" relates to diffuse reflections, "Gloss" to the presence of high contrast sharp specular highlights and "Metallicity" to spread out specular reflections. 1:2 • Toscani et al. in  ...  ACKNOWLEDGMENTS We thank Roland Fleming for helpful discussions and comments. We also thank Anna Metzger for her support in translating German into English for the rating experiment.  ...

Toward a perceptual space for gloss

Josh Wills, Sameer Agarwal, David Kriegman, Serge Belongie
2009 ACM Transactions on Graphics  
The embedding is validated by correlating it with nine gloss dimensions, fitted parameters of seven analytical BRDF models, and a perceptual parameterization of Ward's model.  ...  The data from the psychophysics study and the MDS algorithm is used to construct a low dimensional perceptual embedding of these bidirectional reflectance distribution functions (BRDFs).  ...  Diana Deutsch, Lawrence Cayton and Kristin Branson.  ...

Toward a psychophysically-based light reflection model for image synthesis

Fabio Pellacini, James A. Ferwerda, Donald P. Greenberg
2000 Proceedings of the 27th annual conference on Computer graphics and interactive techniques - SIGGRAPH '00  
The result is a new psychophysically-based light reflection model where the dimensions of the model are perceptually meaningful, and variations along the dimensions are perceptually uniform.  ...  To develop the model, we've conducted two experiments that explore the relationships between the physical parameters used to describe the reflectance properties of glossy surfaces and the perceptual dimensions  ...  Ward's model uses three parameters to describe the BRDF: ρ d -the object's diffuse reflectance; ρ s -the energy of its specular component, and α -the spread of the specular lobe.  ...

Perceived glossiness and lightness under real-world illumination

M. Olkkonen, D. H. Brainard
2010 Journal of Vision  
For these perceptual representations to be useful, they must correlate with physical reflectance properties of objects and not be overly affected by changes in illumination or viewing context.  ...  Color, lightness, and glossiness are perceptual attributes associated with object reflectance.  ...  The two levels of diffuse reflectance are shown in rows, and the three specularities in columns.  ...

Psychophysically based model of surface gloss perception

James A. Ferwerda, Fabio Pellacini, Donald P. Greenberg, Bernice E. Rogowitz, Thrasyvoulos N. Pappas
2001 Human Vision and Electronic Imaging VI  
We use image synthesis techniques to conduct experiments that explore the relationships between the physical dimensions of glossy reflectance and the perceptual dimensions of glossy appearance.  ...  The product of these experiments is a psychophysically-based model of surface gloss, with dimensions that are both physically and perceptually meaningful and scales that reflect our sensitivity to gloss  ...  and Carol Krumhansl for their insights on data analysis.  ...

Perceptual Gloss Parameters Are Encoded by Population Responses in the Monkey Inferior Temporal Cortex

physical reflectance parameters: specular reflectance (ρs), diffuse reflectance (ρd), and spread of specular reflection (α; Nishio et al., 2012).  ...  In an earlier psychophysical study, Ferwerda et al. (2001) identified a perceptually uniform gloss space defined by two axes where the c-axis corresponds to a nonlinear combination of ρs and ρd and the  ...  A, Schematic illustration of three reflection parameters: diffuse reflectance (d), specular reflectance (s), and spread of specular reflection (␣).  ...

The perception of hazy gloss

Peter Vangorp, Pascal Barla, Roland W. Fleming
2017 Journal of Vision  
However, BRDFs can be substantially more complex and it is interesting to ask how many additional perceptual dimensions there could be in the visual representation of surface reflectance qualities.  ...  The results reveal an additional perceptual dimension of gloss-beyond strength and sharpnessakin to "haze gloss" (Hunter & Harold, 1987) .  ...  This suggests that haze truly is a distinct perceptual dimension of reflectance, independent of blur, and associated with the presence of both sharp and blurry reflections simultaneously.  ...

Material category determined by specular reflection structure mediates the processing of image features for perceived gloss [article]

Alexandra C. Schmid, Pascal Barla, Katja Doerschner
2020 bioRxiv   pre-print
We measure visual (image) features that predict these changes in appearance, and causally manipulate these features to confirm their role in perceptual categorisation.  ...  We report a series of experiments that show that parametrically changing reflectance parameters leads to qualitative changes in material appearance beyond those expected by the reflectance function used  ...  We thank Chris Baker for helpful comments on earlier versions of this manuscript.  ...

Improved Intuitive Appearance Editing based on Soft PCA [article]

Sandra Malpica, Miguel Barrio, Diego Gutierrez, Ana Serrano, Belen Masia
2017 Spanish Computer Graphics Conference (CEIG)  
In this paper, we build on top of their work and propose to use two separate PCA bases for representing specular and diffuse BRDFs, and map each of these bases to the perceptual attributes.  ...  This PCA representation is biased towards specular materials and fails to represent very diffuse BRDFs, therefore producing unpleasant artifacts when editing.  ...  Figure 7 7 Figure7shows the specularity value for the 406 BRDFs used in the attribute training in the previous section, each one of them projected in the first three dimensions of the PCA components for  ...

Precedence effect for specular and diffuse reflections

Florian Wendt, Robert Höldrich
2020 Acta Acustica  
The perceptual influences of diffusion are studied in a listening experiment; echo thresholds and masked thresholds of specular and diffuse reflections are measured.  ...  Results show that diffusion makes the reflections more easily detectable than specular reflections of the same total energy.  ...  We would like to thank all listeners for their participation in the experiments.  ...
