    • Modelling of Clouds from a Hemispherical Image 

      Alldieck, Thiemo; Lundtoft, Dennis H.; Montanari, Niels; Nikolov, Ivan; Vlaykov, Iskren G.; Madsen, Claus B. (The Eurographics Association, 2014)
      This paper presents an image-based method for modelling clouds. Unlike previous image-based approaches, a hemispherical photograph is used as input, enabling to consider an entire sky instead of merely a portion. Our method ...

    • A Study on Glyph-based Visualisation with Dense Visual Context 

      Khan, Saiful; Proctor, Karl J.; Walton, Simon; Bañares-Alcántara, René; Chen, Min (The Eurographics Association, 2014)
      In a focus+context visualization, one often finds it difficult to overlay focus information on top of a dense visual context. This work is motivated by a need for visualizing search results (i.e., focus) in relation to a ...

    • Variations on Image Reconstruction:Weighted Back Projection and Fourier Expectation Maximization 

      Ryan, Andrew; Mora, B. (The Eurographics Association, 2014)
      Expectation Maximization and Filtered Back Projection are two common techniques for Tomographic reconstruction of images and volumes. While papers often demonstrat that EM produces higher quality reconstructions, particularly ...

    • Visual Analysis of Hurricane Data Using Joint Contour Net 

      Geng, Zhao; Duke, David; Carr, Hamish; Chattopadhyay, Amit (The Eurographics Association, 2014)
      Topology provides a rigorous foundation for identifying features and transitions within data. However, computing and presenting topological features in multi-dimensional range space is still a difficult problem. The Joint ...
