However, time-resolved illumination measurements are high-dimensional and have a low signal-to-noise ratio, hampering their applicability in real scenarios. We propose a novel method to compactly represent time-resolved illumination using mixtures of exponentially modified Gaussians that are robust to noise and preserve structural information. Our method yields representations two orders of magnitude smaller than discretized data, providing consistent results in such applications as hidden-scene reconstruction and depth estimation, and quantitative improvements over previous approaches. info:eu-repo/grantAgreement/ES/AEI/PID2019-105004GB-I00 info:eu-repo/grantAgreement/ES/DGA/LMP30-21 info:eu-repo/grantAgreement/EC/H2020/682080/EU/Intuitive editing of visual appearance from real-world datasets/CHAMELEON This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 682080-CHAMELEON info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 3.6 2022 OPTICS 31 / 99 = 0.313 2022 Q2 T1 1.179 2022 Atomic and Molecular Physics, and Optics 2022 Q1 7.0 2022 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Huang, Zesheng Liang, Yun Song, Boyan Muñoz, Adolfo Universidad de Zaragoza (orcid)0000-0002-8160-7159 Gutierrez, Diego Universidad de Zaragoza (orcid)0000-0002-7503-7022 Marco, Julio Universidad de Zaragoza (orcid)0000-0001-9960-8945 5007 570 Universidad de Zaragoza Dpto.
