    • Compressive High Speed Video Acquisition 

      Serrano, Ana; Gutierrez, Diego; Masia, Belen (The Eurographics Association, 2015)
      Traditional video capture is limited by the trade-off between spatial and temporal resolution. When capturing videos of high temporal resolution, the spatial resolutions decreases due to bandwidth limitations in the capture ...

    • Convolutional Sparse Coding for Capturing High‐Speed Video Content 

      Serrano, Ana; Garces, Elena; Masia, Belen; Gutierrez, Diego (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Video capture is limited by the trade‐off between spatial and temporal resolution: when capturing videos of high temporal resolution, the spatial resolution decreases due to bandwidth limitations in the capture system. ...

    • Fast Generation of Approximate Blue Noise Point Sets 

      Kalantari, Nima Khademi; Sen, Pradeep (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Poisson-disk sampling is a popular sampling method because of its blue noise power spectrum, but generation of these samples is computationally very expensive. In this paper, we propose an efficient method for fast generation ...

    • Feature-preserving Direct Blue Noise Sampling for Surface Meshes 

      Peyrot, Jean-Luc; Payan, Frédéric; Antonini, Marc (The Eurographics Association, 2013)
      We present a new direct Poisson disk sampling for surface meshes. Our objective is to sample triangular meshes, while satisfying good blue noise properties, but also preserving features. Our method combines a feature ...

    • General Point Sampling with Adaptive Density and Correlations 

      Roveri, Riccardo; Öztireli, A. Cengiz; Gross, Markus (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Analyzing and generating sampling patterns are fundamental problems for many applications in computer graphics. Ideally, point patterns should conform to the problem at hand with spatially adaptive density and correlations. ...

    • Parallel Blue-noise Sampling by Constrained Farthest Point Optimization 

      Chen, Renjie; Gotsman, Craig (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We describe a fast sampling algorithm for generating uniformly-distributed point patterns with good blue noise characteristics. The method, based on constrained farthest point optimization, is provably optimal and may be ...

    • PixelPie: Maximal Poisson-disk Sampling with Rasterization 

      Ip, Cheuk Yiu; Yalc, M. Adil; Luebke, David; Varshney, Amitabh (ACM, 2013)
      We present PixelPie, a highly parallel geometric formulation of the Poisson-disk sampling problem on the graphics pipeline. Traditionally, generating a distribution by throwing darts and removing conflicts has been viewed ...

    • Random Sparse Coded Aperture for Lensless Imaging 

      Wang, Zhenglin; Lee, Ivan (The Eurographics Association, 2014)
      This paper develops a computational lensless imaging system based on a random sparse coded aperture. The camera consists of a thin mask with a coded pattern and a standard sensor array. The proposed coded aperture contains ...

    • View-independent Environment Maps 

      Heidrich, Wolfgang; Seidel, Hans-Peter (The Eurographics Association, 1998)
      Environment maps are widely used for approximating reflections in hardware-accelerated rendering applications. Unfortunately, the parameterizations for environment maps used in today s graphics hardware severely undersample ...
