    • Object-aware Gradient-Domain Image Compositing 

      Eisemann, Martin; Kokemüller, Jan; Magnor, Marcus (The Eurographics Association, 2011)
      We describe an approach to suppress bleeding artifacts without altering the boundary location in gradient-domain compositing, a technique to create seamless composites. While gradient-domain compositing has become a stan- ...
    • Objective Finite-Time Saddles and their Connection to FTLE 

      Bujack, Roxana; Dutta, Soumya; Rojo, Irene Baeza; Zhang, Duan; Günther, Tobias (The Eurographics Association, 2019)
      Based on an intuitive physical definition of what a finite-time saddle-like behavior is, we derive a mathematical definition. We show that this definition builds the link between two FTLE-based saddle generalizations, which ...
    • An Occlusion Culling Toolkit for OpenSG PLUS 

      Staneker, Dirk (The Eurographics Association, 2003)
      Image-space occlusion culling is an useful approach to reduce the rendering load of large polygonal models in scienti c computing, mechanical engineering, or virtual medicine. Like most large model techniques, occlusion ...
    • Occlusion-Based Snow Accumulation Simulation 

      Foldes, David; Benes, Bedrich (The Eurographics Association, 2007)
      We present a fast technique for the simulation of accumulated snow. Our technique is based on two phenomena; local occlusion of small holes and ditches, and the global influence of a skylight. We use ambient occlusion to ...
    • OceanPaths: Visualizing Multivariate Oceanography Data 

      Nobre, Carolina; Lex, Alexander (The Eurographics Association, 2015)
      Geographical datasets are ubiquitous in oceanography. While map-based visualizations are useful for many different domains, they can suffer from cluttering and overplotting issues when used for multivariate data sets. As ...
    • OCTAVIS: An Easy-to-Use VR-System for Clinical Studies 

      Dyck, Eugen; Zell, Eduard; Kohsik, Agnes; Grewe, Philip; Winter, York; Piefke, Martina; Botsch, Mario (The Eurographics Association, 2012)
      We present the OCTAVIS system, a novel virtual reality platform developed for rehabilitation and training of patients with brain function disorders. To meet the special requirements of clinical studies, our system has been ...
    • On Close and Distant Reading in Digital Humanities: A Survey and Future Challenges 

      Jänicke, Stefan; Franzini, Greta; Cheema, Muhammad Faisal; Scheuermann, Gerik (The Eurographics Association, 2015)
      We present an overview of the last ten years of research on visualizations that support close and distant reading of textual data in the digital humanities. We look at various works published within both the visualization ...
    • On Establishing Visualization Requirements: A Case Study in Product Costing 

      Vosough, Zana; Groh, Rainer; Schulz, Hans-Jörg (The Eurographics Association, 2017)
      The process of identifying visualization requirements is an important part of every visualization researcher's and practitioner's job. Nevertheless, the scientific literature is rather sparse on this topic, usually resorting ...
    • On Inconvenient Images: Exploring the Design Space of Engaging Climate Change Visualizations for Public Audiences 

      Windhager, Florian; Schreder, Günther; Mayr, Eva (The Eurographics Association, 2019)
      If there ever was a model theme for information visualization, climate change arguably checks all the boxes. Omnipresent and relevant, yet abstract and statistical by nature, as well as invisible for the naked eye - climate ...
    • On KDE-based Brushing in Scatterplots and how it Compares to CNN-based Brushing 

      Fan, Chaoran; Hauser, Helwig (The Eurographics Association, 2019)
      In this paper, we investigate to which degree the human should be involved into the model design and how good the empirical model can be with more careful design. To find out, we extended our previously published Mahalanobis ...
    • On Quality Indicators for Progressive Visual Analytics 

      Angelini, Marco; May, Thorsten; Santucci, Giuseppe; Schulz, Hans-Jörg (The Eurographics Association, 2019)
      A key component in using Progressive Visual Analytics (PVA) is to be able to gauge the quality of intermediate analysis outcomes. This is necessary in order to decide whether a current partial outcome is already good enough ...
    • On the Beat: Analysing and Evaluating Synchronicity in Dance Performances 

      Menzel, Malte; Tauscher, Jan-Philipp; Magnor, Marcus (The Eurographics Association, 2023)
      This paper presents a method to analyse and evaluate synchronicity in dance performances automatically. Synchronisation of a dancer's movement and the accompanying music is a vital characteristic of dance performances. We ...
    • On the Editing of Images: Selecting, Cutting and Filling-in 

      Labrosse, F. (The Eurographics Association, 2003)
      This paper is two-fold. On the one hand, we present a system using qualitative spatial reasoning to help a user choose parts of an image that form interesting objects. The system then allows the user to cut these parts as ...
    • On the Evaluation of a Semi-Automatic Vortex Flow Classification in 4D PC-MRI Data of the Aorta 

      Meuschke, Monique; Köhler, Ben; Preim, Bernhard; Lawonn, Kai (The Eurographics Association, 2016)
      In this paper, we report on our experiences that we made during our contributions in the field of the visualization of flow characteristics. Mainly, we focused on the vortex flow classification in 4D PC-MRI as current ...
