Beyond Volumetric Albedo--A Surface Optimization Framework for Non-Line-Of-Sight Imaging

CY Tsai, AC Sankaranarayanan… - Proceedings of the …, 2019 - openaccess.thecvf.com
Abstract Non-line-of-sight (NLOS) imaging is the problem of reconstructing properties of
scenes occluded from a sensor, using measurements of light that indirectly travels from the …

High-contrast computational caustic design

Y Schwartzburg, R Testuz, A Tagliasacchi… - ACM Transactions on …, 2014 - dl.acm.org
We present a new algorithm for computational caustic design. Our algorithm solves for the
shape of a transparent object such that the refracted light paints a desired caustic image on …

Non-line-of-sight surface reconstruction using the directional light-cone transform

SI Young, DB Lindell, B Girod… - Proceedings of the …, 2020 - openaccess.thecvf.com
We propose a joint albedo-normal approach to non-line-of-sight (NLOS) surface
reconstruction using the directional light-cone transform (D-LCT). While current NLOS …

State of the art in computational fabrication and display of material appearance

MB Hullin, I Ihrke, W Heidrich, T Weyrich… - Eurographics Annual …, 2013 - inria.hal.science
After decades of research on digital representations of material and object appearance,
computer graphics has more recently turned to the problem of creating physical artifacts with …

Fabricating microgeometry for custom surface reflectance

T Weyrich, P Peers, W Matusik… - ACM Transactions on …, 2009 - dl.acm.org
We propose a system for manufacturing physical surfaces that, in aggregate, exhibit a
desired surface appearance. Our system begins with a user specification of a BRDF, or …

Goal‐based caustics

M Papas, W Jarosz, W Jakob… - Computer Graphics …, 2011 - Wiley Online Library
We propose a novel system for designing and manufacturing surfaces that produce desired
caustic images when illuminated by a light source. Our system is based on a nonnegative …

Photorealistic rendering of mixed reality scenes

J Kronander, F Banterle, A Gardner… - Computer Graphics …, 2015 - Wiley Online Library
Photo‐realistic rendering of virtual objects into real scenes is one of the most important
research problems in computer graphics. Methods for capture and rendering of mixed reality …

Designing illumination lenses and mirrors by the numerical solution of Monge–Ampère equations

K Brix, Y Hafizogullari, A Platen - Journal of the Optical Society of …, 2015 - opg.optica.org
We consider the inverse refractor and the inverse reflector problem. The task is to design a
free-form lens or a free-form mirror that, when illuminated by a point light source, produces a …

Fabricating BRDFs at high spatial resolution using wave optics

A Levin, D Glasner, Y **ong, F Durand… - ACM Transactions on …, 2013 - dl.acm.org
Recent attempts to fabricate surfaces with custom reflectance functions boast impressive
angular resolution, yet their spatial resolution is limited. In this paper we present a method to …

Inverse transport networks

C Che, F Luan, S Zhao, K Bala, I Gkioulekas - arxiv preprint arxiv …, 2018 - arxiv.org
We introduce inverse transport networks as a learning architecture for inverse rendering
problems where, given input image measurements, we seek to infer physical scene …
