  • Virtual Hair Handle: A Model for Haptic Hairstyling 

    Bonanni, Ugo; Kmoch, Petr (The Eurographics Association, 2008)
    The process of styling virtual hair is a tedious task for 3D artists, who would significantly profit from more natural and intuitive ways of creating virtual hairstyles - such as, for example, the possibility to simply ...
  • Identification of Dynamic Mass Spring Parameters for Deformable Body Simulation 

    Lloyd, Bryn; Kirac, S.; Szekely, Gabor; Harders, Matthias (The Eurographics Association, 2008)
    Mass spring systems (MSS) are frequently used to simulate deformable objects because of their conceptual sim- plicity and computational speed. Unfortunately, the model parameters (spring coefficients, masses) are not related ...
  • Level of Detail Flow Simulation 

    Klar, Gergely (The Eurographics Association, 2008)
    In this paper we present a framework to simulate visually plausible large scale flow of fluids or smoke. To maintain real-time speed, we define the simulation over a coarse grid which is refined with a more detailed grid ...
  • Compensation of the Light Attenuation with Depth of Images Captured by a Confocal Microscope Using a MRF Deformation Model and Graph Cuts 

    Capek, Martin; Michalek, Jan; Janacek, Jiri; Kubinova, Lucie; Hana, Karel; Smrcka, Pavel (The Eurographics Association, 2008)
    We study series of fluorescent optical sections, i.e. three-dimensional (3D) biomedical images, captured by a confocal laser scanning microscope (CLSM). Fluorescent image intensities of optical sections from deep layers ...
  • Efficient Spherical Harmonics Lighting with the Preetham Skylight Model 

    Habel, Ralf; Mustata, Bogdan; Wimmer, Michael (The Eurographics Association, 2008)
    We present a fast and compact representation of a skylight model for spherical harmonics lighting, especially for outdoor scenes. This representation allows dynamically changing the sun position and weather conditions on ...
  • Shadowed Relighting of Dynamic Geometry with 1D BRDFs 

    Nowrouzezahrai, Derek; Kalogerakis, Evangelos; Simari, Patricio; Fiume, Eugene (The Eurographics Association, 2008)
    We present a method for synthesizing the dynamic self-occlusion of an articulating character in real-time (> 170Hz) while incorporating reflection effects from 1D BRDFs under dynamic lighting and view conditions. We ...
  • Microquad Soft Shadow Mapping Revisited 

    Schwarz, Michael; Stamminger, Marc (The Eurographics Association, 2008)
    Recently, real-time soft shadow research saw many important contributions from the class of soft shadow mapping algorithms, where approximate occluder geometry is reconstructed from a shadow map and backprojected onto the ...
  • Improving Interaction Performance for Ray Tracing 

    Kurz, Daniel; Lux, Christopher; Springer, Jan P.; Froehlich, Bernd (The Eurographics Association, 2008)
    We have developed an approach for improving the performance of object manipulation in ray tracing systems. We assume that users alternate between navigating the scene and manipulating objects in the scene. We divide the ...
  • Volume Data Visualization Using Fractal Interpolation Surfaces 

    Manousopoulos, Polychronis; Drakopoulos, Vassileios; Theoharis, Theoharis (The Eurographics Association, 2008)
    Visualization of medical or experimental data is often achieved by extracting an intermediate geometric representation of the data. One such popular method for extracting an isosurface from volume data is the Marching Cubes ...
  • Rendering Method for Flat Origami 

    Mitani, Jun (The Eurographics Association, 2008)
    In flat Origami (Origami which is folded flat), some cases exist that have a closed-loop in the overlap order of faces after they are folded. It is difficult to display this shape correctly on the screen when Origami is ...
  • Interactive Stroke-Based NPR using Hand Postures on Large Displays 

    Grubert, Jens; Carpendale, Sheelagh; Isenberg, Tobias (The Eurographics Association, 2008)
    We explore the use of hand postures to interact with stroke-based rendering (SBR) on touch-sensitive large displays. In contrast to traditional WIMP interfaces, we allow people to directly engage with and influence a ...
  • Efficient Visualization of Architectural Models from a Structure and Motion Pipeline 

    Farenzena, Michela; Fusiello, Andrea; Gherardi, Riccardo (The Eurographics Association, 2008)
    State of the art three dimensional reconstruction pipelines can nowadays produce models up to several million polygons without any human intervention from a set of digital images or video. Such models are able to stretch ...
  • Laziness is a Virtue: Motion Stitching Using Effort Minimization 

    Li, Lei; McCann, James; Faloutsos, Christos; Pollard, Nancy (The Eurographics Association, 2008)
    Given two motion-capture sequences that are to be stitched together, how can we assess the goodness of the stitching? The straightforward solution, Euclidean distance, permits counter-intuitive results because it ignores ...
  • FMDistance: A Fast and Effective Distance Function for Motion Capture Data 

    Onuma, Kensuke; Faloutsos, Christos; Hodgins, Jessica K. (The Eurographics Association, 2008)
    Given several motion capture sequences, of similar (but not identical) length, what is a good distance function? We want to find similar sequences, to spot outliers, to create clusters, and to visualize the (large) set of ...
  • Recognition of Human Actions using Layered Hidden Markov Models 

    Perdikis, Serafeim; Tzovaras, Dimitrios; Strintzis, Michael Gerasimos (The Eurographics Association, 2008)
    Human activity recognition has been a major goal of research in the field of human - computer interaction. This paper proposes a method which employs a hierarchical structure of Hidden Markov Models (Layered HMMs) in an ...
  • Contact Skinning 

    Duriez, Christian; Courtecuisse, Hadrien; Alcalde, Juan-Pablo de la Plata; Bensoussan, Pierre-Jean (The Eurographics Association, 2008)
    In this paper, we propose a new approach to model interactions through a skinning method. Skinning is a frequently used technique to animate a mesh based on skeleton motion. In the case of a hand motion sequence used to ...
  • Mining Motifs from Human Motion 

    Meng, Jingjing; Yuan, Junsong; Hans, Mat; Wu, Ying (The Eurographics Association, 2008)
    Mining frequently occurring temporal motion patterns (motion motifs) is important for understanding, organizing and retrieving motion data. However, without any a priori knowledge of the motifs, such as their lengths, ...
  • Revealing Pentimenti Through Raking Angle Photography 

    Cheung, Chi Yin; Mohan, Ankit; Tumblin, Jack (The Eurographics Association, 2008)
    Discovering hidden details in historical paintings, such as pentimenti, can help reveal historical influences and changing intentions of an artist. Top-down photographs of visible light historical paintings do not capture ...
  • Video Carving 

    Chen, Billy; Sen, Pradeep (The Eurographics Association, 2008)
    We present a technique for summarizing a video into a short segment, while preserving the important events in the original. While many techniques remove whole frames from the video stream when condensing it, we observe ...
  • Removing Artifacts Due To Frequency-Domain Processing of Light-Fields 

    Intwala, Chintan; Georgeiv, Todor (The Eurographics Association, 2008)
    In previous works, light-field capture has been analyzed in spatio-angular representation. A light-field camera samples the optical signal within a single photograph by multiplexing the 4D radiance onto the physical 2D ...
