Variable Ring Light Imaging: Capturing Transient Subsurface Scattering with An Ordinary Camera

no code implementations • ECCV 2018 • Ko Nishino, Art Subpa-Asa, Yuta Asano, Mihoko Shimano, Imari Sato

We show that the path length of light captured in each of these observations is naturally lower-bounded by the ring light radius.

Wetness and Color From a Single Multispectral Image

no code implementations • CVPR 2017 • Mihoko Shimano, Hiroki Okawa, Yuta Asano, Ryoma Bise, Ko Nishino, Imari Sato

We derive an analytical spectral appearance model of wet surfaces that expresses the characteristic spectral sharpening due to multiple scattering and absorption in the surface.
