    • Pixel History Linear Models for Real-Time Temporal Filtering 

      Iglesias-Guitian, Jose A.; Moon, Bochang; Koniaris, Charalampos; Smolikowski, Eric; Mitchell, Kenny (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We propose a new real-time temporal filtering and antialiasing (AA) method for rasterization graphics pipelines. Our method is based on Pixel History Linear Models (PHLM), a new concept for modeling the history of pixel ...

    • Pixel Merge Unit 

      Sathe, Rahul; Akenine-Möller, Tomas (The Eurographics Association, 2015)
      Multi-sample anti-aliasing is a popular technique for reducing geometric aliasing (jagged edges) and is supported in all modern graphics processors. With multi-sampling anti-aliasing, visibility and depth are sampled more ...

      This paper presents a new ray-tracing acceleration technique called Pixel Selected Ray-Tracing (PSRT). PSRT uses undersampling based on Iterative Central Point Selection(ICPS) along with checking for similarities among ...

    • Pixel Wise Pie Charts: Placement of Data Points Visualizing Spatial Value Distributions 

      Janetzko, Halldor; Stein, Manuel (The Eurographics Association, 2018)
      Handling overplotted points in spatial pixel-based visualizations is usually done either by aggregation or sampling. The third rather unusual alternative is replacing data items untangling overplotted regions. Depending ...

      We propose a novel approach to learning cloth deformation as a function of body pose, recasting the graph-like triangle mesh data structure into image-based data in order to leverage popular and well-developed convolutional ...

    • Pixel-Based Hyperparameter Selection for Feature-Based Image Registration 

      Brunet, Florent; Bartoli, Adrien; Navab, Nassir; Malgouyres, Rémy (The Eurographics Association, 2010)
      This paper deals with parametric image registration from point correspondences in deformable environments. In this problem, it is essential to determine correct values for hyperparameters such as the number of control ...

    • Pixel-based Wake Interaction and Power Estimation for a Wind Farm with Irregular Boundary 

      Ohlsen, G.; Ruiz-Salguero, O.; Full, T.; Acosta, D. (The Eurographics Association, 2018)
      In the domain of generation of wind turbine energy, it is central to correctly estimate the interactions among the various turbines in a wind turbine farm. The spatial super-position of turbine wind wakes determines the ...

    • Pixel-Correct Shadow Maps with Temporal Reprojection and Shadow Test Confidence 

      Scherzer, Daniel; Jeschke, Stefan; Wimmer, Michael (The Eurographics Association, 2007)
      Shadow mapping suffers from spatial aliasing (visible as blocky shadows) as well as temporal aliasing (visible as flickering). Several methods have already been proposed for reducing such artifacts, but so far none is able ...

    • Pixel-Level Algorithms for Drawing Curves 

      Liu, Yong Kui; Wang, Peng Jie; Zhao, Dan Dan; Spelic, Denis; Mongus, Domen; Zalik, Borut (The Eurographics Association, 2011)
      This paper introduces new pixel level algorithms for parametric curves. The optimal value of the steps is first derived when rastrerizing parametric curves. A double-step algorithm using only integer arithmetic is presented ...

    • A Pixel-Parallelhidden Surface Algorithm For Constructive Solid Geometry 

      Jansen, Frederik W. (The Eurographics Association, 1986)
      VLSI techniques have greatly enlarged the possibilities to design new frame buffer architectures with parallel processing capabilities down to the pixel level. For these pixel processor systems a parallel hidden surface ...

    • Pixel-Planes 4: A Summary 

      Eyles, John; Austint, John; Fuchs, Henry; Greer, Trey; Poulton, John (The Eurographics Association, 1987)
      We describe the current state of the Pixel-planes research project, whose goal is to develop powerful raster graphics systems for the next generation of workstations, The first full-scale prototype has been in regular use ...

    • Pixel-wise Dense Detector for Image Inpainting 

      Zhang, Ruisong; Quan, Weize; Wu, Baoyuan; Li, Zhifeng; Yan, Dong-Ming (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Recent GAN-based image inpainting approaches adopt an average strategy to discriminate the generated image and output a scalar, which inevitably lose the position information of visual artifacts. Moreover, the adversarial ...

    • PIXEL2BRICK: Constructing Brick Sculptures from Pixel Art 

      Kuo, Ming-Hsun; Lin, You-En; Chu, Hung-Kuo; Lee, Ruen-Rone; Yang, Yong-Liang (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      LEGO, a popular brick-based toy construction system, provides an affordable and convenient way of fabricating geometric shapes. However, building arbitrary shapes using LEGO bricks with restrictive colors and sizes is not ...

    • Pixelated Image Abstraction 

      Gerstner, Timothy; DeCarlo, Doug; Alexa, Marc; Finkelstein, Adam; Gingold, Yotam; Nealen, Andrew (The Eurographics Association, 2012)

    • Pixelating Vector Line Art 

      Inglis, Tiffany C.; Kaplan, Craig S. (The Eurographics Association, 2012)
      Creating pixel art is a laborious process that requires artists to place individual pixels by hand. Although many image editors provide vector-to-raster conversions, the results produced do not meet the standards of pixel ...
