    • Deep Shape and SVBRDF Estimation using Smartphone Multi-lens Imaging 

      Fan, Chongrui; Lin, Yiming; Ghosh, Abhijeet (The Eurographics Association and John Wiley & Sons Ltd., 2023)
      We present a deep neural network-based method that acquires high-quality shape and spatially varying reflectance of 3D objects using smartphone multi-lens imaging. Our method acquires two images simultaneously using a zoom ...

    • Frontmatter: Pacific Graphics 2018 

      Fu, Hongbo; Ghosh, Abhijeet; Kopf, Johannes (The Eurographics Association and John Wiley & Sons Ltd., 2018)

    • Frontmatter: Pacific Graphics 2018 - Short Papers and Posters 

      Fu, Hongbo; Ghosh, Abhijeet; Kopf, Johannes (The Eurographics Association, 2018)

    • Neural BTF Compression and Interpolation 

      Rainer, Gilles; Jakob, Wenzel; Ghosh, Abhijeet; Weyrich, Tim (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      The Bidirectional Texture Function (BTF) is a data-driven solution to render materials with complex appearance. A typical capture contains tens of thousands of images of a material sample under varying viewing and lighting ...

    • Neural Shading Fields for Efficient Facial Inverse Rendering 

      Rainer, Gilles; Bridgeman, Lewis; Ghosh, Abhijeet (The Eurographics Association and John Wiley & Sons Ltd., 2023)
      Given a set of unstructured photographs of a subject under unknown lighting, 3D geometry reconstruction is relatively easy, but reflectance estimation remains a challenge. This is because it requires disentangling lighting ...

    • On-Site Example-Based Material Appearance Acquisition 

      Lin, Yiming; Peers, Pieter; Ghosh, Abhijeet (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      We present a novel example-based material appearance modeling method suitable for rapid digital content creation. Our method only requires a single HDR photograph of a homogeneous isotropic dielectric exemplar object under ...

    • Polarization-imaging Surface Reflectometry using Near-field Display 

      Nogue, Emilie; Lin, Yiming; Ghosh, Abhijeet (The Eurographics Association, 2022)
      We present a practical method for measurement of spatially varying isotropic surface reflectance of planar samples using a combination of single-view polarization imaging and near-field display illumination. Unlike previous ...

    • Practical Acquisition of Shape and Plausible Appearance of Reflective and Translucent Objects 

      Lin, Arvin; Lin, Yiming; Ghosh, Abhijeet (The Eurographics Association and John Wiley & Sons Ltd., 2023)
      We present a practical method for acquisition of shape and plausible appearance of reflective and translucent objects for realistic rendering and relighting applications. Such objects are extremely challenging to scan with ...

    • Practical Measurement and Reconstruction of Spectral Skin Reflectance 

      Gitlina, Yuliya; Guarnera, Giuseppe Claudio; Dhillon, Daljit Singh; Hansen, Jan; Lattas, Alexandros; Pai, Dinesh; Ghosh, Abhijeet (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      We present two practical methods for measurement of spectral skin reflectance suited for live subjects, and drive a spectral BSSRDF model with appropriate complexity to match skin appearance in photographs, including human ...

    • Rendering 2022 CGF 41-4: Frontmatter 

      Ghosh, Abhijeet; Wei, Li-Yi (The Eurographics Association and John Wiley & Sons Ltd., 2022)

    • Rendering 2022 Symposium Track: Frontmatter 

      Ghosh, Abhijeet; Wei, Li-Yi (The Eurographics Association, 2022)

    • Spectral Upsampling Approaches for RGB Illumination 

      Guarnera, Giuseppe Claudio; Gitlina, Yuliya; Deschaintre, Valentin; Ghosh, Abhijeet (The Eurographics Association, 2022)
      We present two practical approaches for high fidelity spectral upsampling of previously recorded RGB illumination in the form of an image-based representation such as an RGB light probe. Unlike previous approaches that ...

    • Unified Neural Encoding of BTFs 

      Rainer, Gilles; Ghosh, Abhijeet; Jakob, Wenzel; Weyrich, Tim (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Realistic rendering using discrete reflectance measurements is challenging, because arbitrary directions on the light and view hemispheres are queried at render time, incurring large memory requirements and the need for ...
