    • Dual Illumination Estimation for Robust Exposure Correction 

      Zhang, Qing; Nie, Yongwei; Zheng, Wei-Shi (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Exposure correction is one of the fundamental tasks in image processing and computational photography. While various methods have been proposed, they either fail to produce visually pleasing results, or only work well for ...

    • A Dual Light Stage 

      Hawkins, Tim; Einarsson, Per; Debevec, Paul (The Eurographics Association, 2005)
      We present a technique for capturing high-resolution 4D reflectance fields using the reciprocity property of light transport. In our technique we place the object inside a diffuse spherical shell and scan a laser across ...

    • Dual Marching Cubes: Primal Contouring of Dual Grids 

      Schaefer, Scott; Warren, Joe (The Eurographics Association and Blackwell Publishing Ltd., 2005)
      We present a method for contouring an implicit function using a grid topologically dual to structured grids such as octrees. By aligning the vertices of the dual grid with the features of the implicit function, we are able ...

    • Dual Radial Set 

      Matkovic, Kresimir; Gracanin, Denis; Bardun, Matea; Splechtna, Rainer; Hauser, Helwig (The Eurographics Association, 2020)
      Set-typed data visualizations require novel interactive representations, especially when visualizing multiple set-typed data attributes. The challenge is how to effectively analyze relations between data elements from ...

    • Dual Sheet Meshing: An Interactive Approach to Robust Hexahedralization 

      Takayama, Kenshi (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      The combinatorial dual of a hex mesh induces a collection of mutually intersecting surfaces (dual sheets). Inspired by Campen et al.'s work on quad meshing [CBK12,CK14], we propose to directly generate such dual sheets so ...

    • Dual Streaming for Hardware-Accelerated Ray Tracing 

      Shkurko, Konstantin; Grant, Tim; Kopta, Daniel; Mallett, Ian; Yuksel, Cem; Brunvand, Erik (ACM, 2017)
      Hardware acceleration for ray tracing has been a topic of great interest in computer graphics. However, even with proposed custom hardware, the inherent irregularity in the memory access pattern of ray tracing has limited ...

    • Dual-Color Mixing for Fused Deposition Modeling Printers 

      Reiner, Tim; Carr, Nathan; Mech, Radomir; Stava, Ondrej; Dachsbacher, Carsten; Miller, Gavin (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      In this work we detail a method that leverages the two color heads of recent low-end fused deposition modeling (FDM) 3D printers to produce continuous tone imagery. The challenge behind producing such two-tone imagery is ...

    • Dual-Domain Visual Exploration of Urban Solar Potential 

      Seipel, Stefan; Lingfors, David; Widén, Joakim (The Eurographics Association, 2013)
      Traditional methods for estimating the solar energy potential in buildings determine energy yields on an annual base and make use of highly aggregated geo-spatial data. This work proposes a method for detailed assessment ...

    • The Dual-microfacet Model for Capturing Thin Transparent Slabs 

      Dai, Qiang; Wang, Jiaping; Liu, Yiming; Snyder, John; Wu, Enhua; Guo, Baining (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We present a new model, called the dual-microfacet, for those materials such as paper and plastic formed by a thin, transparent slab lying between two surfaces of spatially varying roughness. Light transmission through the ...

    • DualNetView: Dual Views for Visualizing the Dynamics of Networks 

      Pham, Vung; Nguyen, V. T. Ngan; Dang, Tommy (The Eurographics Association, 2020)
      The force-directed layout is a popular visual method for revealing network structures, such as clusters and important vertices. However, it is not capable of representing temporal patterns, such as how clusters/communities ...

    • DuctTake: Spatiotemporal Video Compositing 

      Rüegg, Jan; Wang, Oliver; Smolic, Aljoscha; Gross, Markus (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      DuctTake is a system designed to enable practical compositing of multiple takes of a scene into a single video. Current industry solutions are based around object segmentation, a hard problem that requires extensive manual ...

    • DUODECIM - A Structure for Point Scan Compression and Rendering 

      Krüger, Jens; Schneider, Jens; Westermann, Rüdiger (The Eurographics Association, 2005)
      In this paper we present a compression scheme for large point scans including per-point normals. For the encoding of such scans we introduce a particular type of closest sphere packing grids, the hexagonal close packing ...

    • Duotone Surfaces 

      Garigipati, Pradeep; Akleman, Ergun (The Eurographics Association, 2012)
      In this paper, we present a method to divide any given surface into two regions with two properties: (1) they are visually interlocked since the boundary curve covers the whole surface by meandering over it and (2) the ...

    • Dupin Cyclide Blends Between Quadric Surfaces for Shape Modeling 

      Foufou, Sebti; Garnier, Lionel (The Eurographics Association and Blackwell Publishing, Inc, 2004)
