The Graphics Lab: “Acquiring Reflectance and Shape from Continuous Spherical Harmonic Illumination”

July 24, 2013 | Anaheim, CA

Speaker: Borom Tunwattanapong, Graham Fyffe, Paul Graham, Jay Busch, XueMing Yu, Abhijeet Ghosh and Paul Debevec

Abstract: A new reflectance measurement and 3D scanning technique uses a rotating arc of light and long-exposure photography to illuminate an object with spherical harmonic illumination and estimate maps from multiple viewpoints. The responses yield estimates of diffuse and specular reflectance parameters and 3D geometry.
