However, current polarimetric acquisition systems are limited to static and opaque objects. Human faces, on the other hand, present a particularly difficult challenge, given their complex structure and reflectance properties, the strong presence of spatially-varying subsurface scattering, and their dynamic nature. We present a new polarimetric acquisition method for dynamic human faces, which focuses on capturing spatially varying appearance and precise geometry, across a wide spectrum of skin tones and facial expressions. It includes both single and heterogeneous subsurface scattering, index of refraction, and specular roughness and intensity, among other parameters, while revealing biophysically-based components such as inner- and outer-layer hemoglobin, eumelanin and pheomelanin. Our method leverages such components' unique multispectral absorption profiles to quantify their concentrations, which in turn inform our model about the complex interactions occurring within the skin layers. To our knowledge, our work is the first to simultaneously acquire polarimetric and spectral reflectance information alongside biophysically-based skin parameters and geometry of dynamic human faces. Moreover, our polarimetric skin model integrates seamlessly into various rendering pipelines. info:eu-repo/semantics/openAccess by-nc-sa https://creativecommons.org/licenses/by-nc-sa/4.0/deed.es 9.5 2024 COMPUTER SCIENCE, SOFTWARE ENGINEERING 5 / 129 = 0.039 2024 Q1 T1 2.965 2024 Computer Graphics and Computer-Aided Design 2024 Q1 17.7 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Hwang, Inseung Monzon, Nestor Universidad de Zaragoza (orcid)0000-0002-5323-3233 Cho, Jaemin Kim, Donggun Baek, Seung-Hwan Muñoz, Adolfo Universidad de Zaragoza (orcid)0000-0002-8160-7159 Gutierrez, Diego Universidad de Zaragoza (orcid)0000-0002-7503-7022 Kim, Min H. 5007 570 Universidad de Zaragoza Dpto.
