Retrographic sensing for the measurement of surface texture and shape
We describe a novel device that can be used as a 2.5D “scanner” for acquiring surface texture and shape. The device consists of a slab of clear elastomer covered with a refl...

Toward Reconstructing Surfaces With Arbitrary Isotropic Reflectance : A Stratified Photometric Stereo Approach
We consider the problem of reconstructing the shape of a surface with an arbitrary, spatially varying isotropic bidirectional reflectance distribution function (BRDF), and introdu...

A Stochastic Model for Non-Stationary Outdoor K-Factor Variation
— A dense urban cellular environment contains many different locations where a line-of-sight or specular signal component from the base station is present. The small scale fading...

X-toon: an extended toon shader
: Some example effects achieved by our extended toon shader: continuous levels of abstraction (a); abstraction of near-silhouette regions: smoothing (b), and opacity (c); backlight...

Efficient Photometric Stereo Technique for Three-Dimensional Surfaces with Unknown BRDF
The present paper focuses on efficient inverse rendering using a Photometric Stereo technique for realistic surfaces. The technique primarily assumes the Lambertian reflection mod...
