    • Ensemble Learning for Reectometry 

      Romeiro, Fabiano; Zickler, Todd (2010)
      In “Blind Reflectometry” (Romeiro and Zickler, 2010 [3]) we describe a variational Bayesian approach to inferring material properties (BRDF) from a single image of a known shape under unknown, real-world illumination. This ...

    • Inferring Reflectance under Real-world Illumination 

      Romeiro, Fabiano; Zickler, Todd (2010)
      We address the problem of inferring homogeneous reflectance (BRDF) from a single image of a known shape in an unknown real-world lighting environment. With appropriate representations of lighting and reflectance, the image ...

    • What Do Color Changes Reveal About an Outdoor Scene? 

      Sunkavalli, Kalyan Krishna; Romeiro, Fabiano Segadaes; Matusik, Wojciech; Zickler, Todd; Pfister, Hanspeter (Institute of Electrical and Electronics Engineers, 2008)
      In an extended image sequence of an outdoor scene, one observes changes in color induced by variations in the spectral composition of daylight. This paper proposes a model for these temporal color changes and explores its ...
