    • Information Visualization on Organized Crime Trials 

      Silvestro, Lorenzo Di; Gallo, Giovanni; Giuffrida, Giovanni; Zarba, Calogero (The Eurographics Association, 2011)
      Today everyone on the Internet becomes an active writer. It is simpler than ever to produce and to share new knowledge on the net. Users risk to be overwhelmed by too such information. To handle unorganized data may involve ...

    • Information Visualization using Transparent Shape Impostors 

      Seipel, Stefan (Eurographics Association, 2003)
      Transparency is a graphical effect used in visualizations to present co-located graphical glyphs. Accomplishing a visually convincing transparency effect requires complex calculations of light absorption and refraction in ...

    • Information-based Feature Enhancement in Scientific Visualization 

      Haidacher, Martin (Haidacher, 2011)

    • Information-based Transfer Functions for Multimodal Visualization 

      Haidacher, Martin; Bruckner, Stefan; Kanitsar, Armin; Gröller, M. Eduard (The Eurographics Association, 2008)
      Transfer functions are an essential part of volume visualization. In multimodal visualization at least two values exist at every sample point. Additionally, other parameters, such as gradient magnitude, are often retrieved ...

    • Information-Guided Transfer Function Refinement 

      Luo, Shengzhou; Dingliana, John (The Eurographics Association, 2014)
      This paper examines the methods for exploring volume data by optimization of visualization parameters. The size and complexity of the parameter space controlling the rendering process makes it challenging to generate an ...

    • An Information-Theoretic Ambient Occlusion 

      González, Francisco; Sbert, Mateu; Feixas, Miquel (The Eurographics Association, 2007)
      Ambient occlusion is a powerful technique that mimics indirect global illumination at a fraction of the cost. In this paper, we introduce a new ambient occlusion technique based on information-theoretic concepts. A viewpoint ...

    • An Information-Theoretic Framework for Image Complexity 

      Rigau, Jaume; Feixas, Miquel; Sbert, Mateu (The Eurographics Association, 2005)
      In this paper, we introduce a new information-theoretic approach to study the complexity of an image. The new framework we present here is based on considering the information channel that goes from the histogram to the ...

    • An Information-Theoretic Observation Channel for Volume Visualization 

      Bramon, Roger; Ruiz, Marc; Bardera, Anton; Boada, Imma; Feixas, Miquel; Sbert, Mateu (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Different quality metrics have been proposed in the literature to evaluate how well a visualization represents the underlying data. In this paper, we present a new information-theoretic framework that quantifies the ...

    • Information-Theoretic Oracle Based on Kernel Smoothness for Hierarchical Radiosity 

      Feixas, Miquel; Rigau, Jaume; Bekaert, Philippe; Sbert, Mateu (Eurographics Association, 2002)
      One of the main problems in the radiosity method is how to discretise the surfaces of a scene into mesh elements that allow us to accurately represent illumination. In this paper we present a robust information-theoretic ...

    • An Information-theoretic Visual Analysis Framework for Convolutional Neural Networks 

      Shen, Jingyi; Shen, Han-Wei (The Eurographics Association, 2021)
      Despite the great success of Convolutional Neural Networks (CNNs) in Computer Vision and Natural Language Processing, the working mechanism behind CNNs is still under extensive discussion and research. Driven by strong ...

    • Informational Dialogue with Van Gogh's Paintings 

      Rigau, Jaume; Feixas, Miquel; Sbert, Mateu (The Eurographics Association, 2008)
      From the pioneering work by Birkhoff, several measures have been proposed to quantify the aesthetic content of art. After Bense's application of information theory to Birkhoff's ideas, the concept of informational aesthetics ...

    • Informative Descriptor Preservation via Commutativity for Shape Matching 

      Nogneng, Dorian; Ovsjanikov, Maks (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We consider the problem of non-rigid shape matching, and specifically the functional maps framework that was recently proposed to find correspondences between shapes. A key step in this framework is to formulate descriptor ...
