    • Object Repositioning Based on the Perspective in a Single Image 

      Iizuka, S.; Endo, Y.; Hirose, M.; Kanamori, Y.; Mitani, J.; Fukui, Y. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We propose an image editing system for repositioning objects in a single image based on the perspective of the scene. In our system, an input image is transformed into a layer structure that is composed of object layers ...

    • Higher Order Ray Marching 

      Muñoz, Adolfo (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Rendering participating media is still a challenging and time consuming task. In such media light interacts at every differential point of its path. Several rendering algorithms are based on ray marching: dividing the path ...

    • Spectral Analysis on Medial Axis of 2D Shapes 

      He, Shuiqing; Choi, Yi‐King; Guo, Yanwen; Wang, Wenping (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Shape analysis finds many important applications in shape understanding, matching and retrieval. Among the various shape analysis methods, spectral shape analysis aims to study the spectrum of the Laplace–Beltrami operator ...

    • Managing Spatial Selections With Contextual Snapshots 

      Mindek, P.; Gröller, M. E.; Bruckner, S. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Spatial selections are a ubiquitous concept in visualization. By localizing particular features, they can be analysed and compared in different views. However, the semantics of such selections often depend on specific ...

    • A Projective Framework for Polyhedral Mesh Modelling 

      Vaxman, Amir (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We present a novel framework for polyhedral mesh editing with face‐based projective maps that preserves planarity by definition. Such meshes are essential in the field of architectural design and rationalization. By using ...

    • The PAG Crowd: A Graph Based Approach for Efficient Data‐Driven Crowd Simulation 

      Charalambous, P.; Chrysanthou, Y. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We present a data‐driven method for the real‐time synthesis of believable steering behaviours for virtual crowds. The proposed method interlinks the input examples into a structure we call the perception‐action graph (PAG) ...

    • Variational Tree Synthesis 

      Wang, Rui; Yang, Yinhui; Zhang, Hongxin; Bao, Hujun (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Modelling trees according to desired shapes is important for many applications. Despite numerous methods having been proposed in tree modelling, it is still a non‐trivial task and challenging. In this paper, we present a ...

    • Group‐in‐a‐Box Meta‐Layouts for Topological Clusters and Attribute‐Based Groups: Space‐Efficient Visualizations of Network Communities and Their Ties 

      Chaturvedi, S.; Dunne, C.; Ashktorab, Z.; Zachariah, R.; Shneiderman, B. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      An important part of network analysis is understanding community structures like topological clusters and attribute‐based groups. Standard approaches for showing communities using colour, shape, rectangular bounding boxes, ...

    • Quad Layout Embedding via Aligned Parameterization 

      Campen, M.; Kobbelt, L. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Quad layouting, i.e. the partitioning of a surface into a coarse network of quadrilateral patches, is a fundamental step in application scenarios ranging from animation and simulation to reverse engineering and meshing. ...

    • Structural Analysis of Multivariate Point Clouds Using Simplicial Chains 

      Rieck, B.; Leitte, H. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Topological and geometrical methods constitute common tools for the analysis of high‐dimensional scientific data sets. Geometrical methods such as projection algorithms focus on preserving distances in the data set. ...

    • Exemplar‐Based Portrait Photograph Enhancement as Informed by Portrait Paintings 

      Zhang, Xiaoyan; Constable, Martin; Chan, Kap Luk (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      This paper proposes an approach to enhance the regional contrasts in snap‐shot style portrait photographs by using pre‐modern portrait paintings as aesthetic exemplars. The example portrait painting is selected based on a ...

    • Adaptive Surface Visualization of Vessels with Animated Blood Flow 

      Lawonn, Kai; Gasteiger, Rocco; Preim, Bernhard (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      The investigation of hemodynamic information for the assessment of cardiovascular diseases (CVDs) gained importance in recent years. Improved flow measuring modalities and computational fluid dynamics (CFD) simulations ...

    • Real-Time Modelling of Fibrous Muscle 

      Kohout, J.; Kukacka, M. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
