    • Label Placement for Outliers in Scatterplots 

      Mumtaz, Haris; Garderen, Mereke van; Beck, Fabian; Weiskopf, Daniel (The Eurographics Association, 2019)
      In many application scenarios, outliers can be associated with specific importance for various reasons. In such cases, labeling outliers is important to connect them to the actual semantics of the respective entity. In ...

      The app ''Labyrinth of Fables'' provides a virtual reality/augmented reality reconstruction of the longlost Labyrinthe of Versailles.
    • A Lagrangian Approach to Dynamic Interfaces through Kinetic Triangulation of the Ambient Space 

      Pons, J.-P.; Boissonnat, J.-D. (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      In this paper, we propose a robust and efficient Lagrangian approach for modeling dynamic interfaces between different materials undergoing large deformations and topology changes, in two dimensions. Our work brings an ...
    • Lagrangian Coherent Structures with Guaranteed Material Separation 

      Germer, Tobias; Otto, Mathias; Peikert, R.; Theisel, H. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Given an unsteady flow field, one common way to compute Lagrangian Coherent Structures (LCS) is to extract extremal structures of the Finite Time Lyapunov Exponent (FTLE). Experience has shown that the resulting structures ...
    • Lagrangian Visualization of Flow-Embedded Surface Structures 

      Garth, Christoph; Wiebel, Alexander; Tricoche, Xavier; Joy, Ken; Scheuermann, Gerik (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      The notions of Finite-Time Lyapunov Exponent (FTLE) and Lagrangian Coherent Structures provide a strong framework for the analysis and visualization of complex technical flows. Their definition is simple and intuitive, and ...
    • Lambertian Correction for Rough and Specular Surfaces 

      Robles-Kelly, A.; Hancock, E.R. (The Eurographics Association, 2003)
      This paper describes a method for performing Lambertian reflectance for rough and specular surfaces. Rather than using an existing reflectance model, we present a method for estimating the reflectance function from image ...
    • Landmark-constrained 3-D Histological Imaging: A Morphology-preserving Approach 

      Gaffling, Simone; Daum, Volker; Hornegger, Joachim (The Eurographics Association, 2011)
      The inspection of histological image sequences to gain knowledge about the original three-dimensional (3-D) morphological structure is a standard method in medical research. Its main advantage is that light microscopes ...
    • Landmark-Guided Elastic Shape Analysis of Spherically-Parameterized Surfaces 

      Kurtek, Sebastian; Srivastava, Anuj; Klassen, Eric; Laga, Hamid (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We argue that full surface correspondence (registration) and optimal deformations (geodesics) are two related problems and propose a framework that solves them simultaneously. We build on the Riemannian shape analysis of ...
    • Landscaper: A Modeling System for 3D Printing Scale Models of Landscapes 

      Allahverdi, Kamyar; Djavaherpour, Hessam; Mahdavi-Amiri, Ali; Samavati, Faramarz (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Landscape models of geospatial regions provide an intuitive mechanism for exploring complex geospatial information. However, the methods currently used to create these scale models require a large amount of resources, which ...
    • Landscapes Synthesis Achieved through Erosion and Deposition Process Simulation
