  Prada, Fabian; Kazhdan, Misha (The Eurographics Association and John Wiley & Sons Ltd., 2015)

  This work revisits the Shock Filters of Osher and Rudin [OR90] and shows how the proposed filtering process can be interpreted as the advection of image values along flow-lines. Using this interpretation, we obtain an ...

• An Image Degradation Model for Depth-augmented Image Editing 

  Hennessey, James W.; Mitra, Niloy J. (The Eurographics Association and John Wiley & Sons Ltd., 2015)

  Images remain the most popular medium to capture our surroundings. Although significant advances have been made in developing image editing tools, the key challenge is to intelligently account for missing depth information. ...

• Dynamic SfM: Detecting Scene Changes from Image Pairs 

  Wang, Tuanfeng Y.; Kohli, Pushmeet; Mitra, Niloy J. (The Eurographics Association and John Wiley & Sons Ltd., 2015)

  Detecting changes in scenes is important in many scene understanding tasks. In this paper, we pursue this goal simply from a pair of image recordings. Specifically, our goal is to infer what the objects are, how they are ...

• Quaternion Julia Set Shape Optimization 

  Kim, Theodore (The Eurographics Association and John Wiley & Sons Ltd., 2015)

  We present the first 3D algorithm capable of answering the question: what would a Mandelbrot-like set in the shape of a bunny look like? More concretely, can we find an iterated quaternion rational map whose potential field ...

• Fast and Exact (Poisson) Solvers on Symmetric Geometries 

  Kazhdan, Misha (The Eurographics Association and John Wiley & Sons Ltd., 2015)

  In computer graphics, numerous geometry processing applications reduce to the solution of a Poisson equation. When considering geometries with symmetry, a natural question to consider is whether and how the symmetry can ...

• LeSSS: Learned Shared Semantic Spaces for Relating Multi-Modal Representations of 3D Shapes 

  Herzog, Robert; Mewes, Daniel; Wand, Michael; Guibas, Leonidas; Seidel, Hans-Peter (The Eurographics Association and John Wiley & Sons Ltd., 2015)

  In this paper, we propose a new method for structuring multi-modal representations of shapes according to semantic relations. We learn a metric that links semantically similar objects represented in different modalities. ...

• Continuous Matching via Vector Field Flow 

  Corman, Etienne; Ovsjanikov, Maks; Chambolle, Antonin (The Eurographics Association and John Wiley & Sons Ltd., 2015)

  We present a new method for non-rigid shape matching designed to enforce continuity of the resulting correspondence. Our method is based on the recently proposed functional map representation, which allows efficient ...

• Tight Relaxation of Quadratic Matching 

  Kezurer, Itay; Kovalsky, Shahar Z.; Basri, Ronen; Lipman, Yaron (The Eurographics Association and John Wiley & Sons Ltd., 2015)

  Establishing point correspondences between shapes is extremely challenging as it involves both finding sets of semantically persistent feature points, as well as their combinatorial matching.We focus on the latter and ...

• Robust Articulated-ICP for Real-Time Hand Tracking 

  Tagliasacchi, Andrea; Schröder, Matthias; Tkach, Anastasia; Bouaziz, Sofien; Botsch, Mario; Pauly, Mark (The Eurographics Association and John Wiley & Sons Ltd., 2015)

  We present a robust method for capturing articulated hand motions in realtime using a single depth camera. Our system is based on a realtime registration process that accurately reconstructs hand poses by fitting a 3D ...

• Sparse Non-rigid Registration of 3D Shapes 

  Yang, Jingyu; Li, Ke; Li, Kun; Lai, Yu-Kun (The Eurographics Association and John Wiley & Sons Ltd., 2015)

  Non-rigid registration of 3D shapes is an essential task of increasing importance as commodity depth sensors become more widely available for scanning dynamic scenes. Non-rigid registration is much more challenging than ...

• Hierarchical Multiview Rigid Registration 

  Tang, Yizhi; Feng, Jieqing (The Eurographics Association and John Wiley & Sons Ltd., 2015)

  In the digital world, assigning arbitrary colors to an object is a simple operation thanks to texture mapping. However, in the real world, the same basic function of applying colors onto an object is far from trivial. One ...

• Reforming Shapes for Material-aware Fabrication 

  Yang, Yong-Liang; Wang, Jun; Mitra, Niloy J. (The Eurographics Association and John Wiley & Sons Ltd., 2015)
