Estimating Specular Normals From Spherical Stokes Reflectance Fields

This talk analyzes the view-independent symmetric Stokes reflectance field under constant-incident spherical illumination, which is either circularly polarized, or unpolarized, and demonstrates that both types of incident lighting can be used to reliably estimate specular normals.

Improved Linear-Light-Source Material Reflectance Scanning

A new device for digitizing reflectance of spatially varying materials such as leather, brushed metal, plastic, paint, and cloth using linear-ligh-source reflectometry that improves on the resolution, accuracy, and efficiency of the approach with several hardware innovations and algorithmic improvements.
