      We present a novel procedural framework for interactively modeling building façades. Common procedural approaches, such as shape grammars, assume that building façades are organized in a tree structure, while in practice ...
    • VDub: Modifying Face Video of Actors for Plausible Visual Alignment to a Dubbed Audio Track 

      Garrido, Pablo; Valgaerts, Levi; Sarmadi, Hamid; Steiner, Ingmar; Varanasi, Kiran; Perez, Patrick; Theobalt, Christian (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      In many countries, foreign movies and TV productions are dubbed, i.e., the original voice of an actor is replaced with a translation that is spoken by a dubbing actor in the country's own language. Dubbing is a complex ...
    • Interactive Generation of Realistic Facial Wrinkles from Sketchy Drawings 

      Kim, Hyeon-Joong; Öztireli, A. Cengiz; Shin, Il-Kyu; Gross, Markus; Choi, Soo-Mi (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Synthesizing facial wrinkles has been tackled either by a long process of manual sculpting on 3D models, or using automatic methods that do not allow for user interaction or artistic expression. In this paper, we propose ...
    • Comprehensible Video Thumbnails 

      Kim, Jongdae; Gray, Charles; Asente, Paul; Collomosse, John (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present the Comprehensible Video Thumbnail; an automatically generated visual précis that summarizes salient objects and their dynamics within a video clip. Salient moving objects are detected within clips using a novel ...
    • IsoMatch: Creating Informative Grid Layouts 

      Fried, Ohad; DiVerdi, Stephen; Halber, Maciej; Sizikova, Elena; Finkelstein, Adam (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Collections of objects such as images are often presented visually in a grid because it is a compact representation that lends itself well for search and exploration. Most grid layouts are sorted using very basic criteria, ...
    • Guiding Image Manipulations using Shape-appearance Subspaces from Co-alignment of Image Collections 

      Nguyen, Chuong H.; Nalbach, Oliver; Ritschel, Tobias; Seidel, Hans-Peter (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We propose a system to restrict the manipulation of shape and appearance in an image to a valid subspace which we learn from a collection of exemplar images. To this end, we automatically co-align a collection of images ...
    • Distilled Collections from Textual Image Queries 

      Averbuch-Elor, Hadar; Wan, Yunhai; Qian, Yiming; Gong, Minglun; Kopf, Johannes; Zhang, Hao; Cohen-Or, Daniel (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present a distillation algorithm which operates on a large, unstructured, and noisy collection of internet images returned from an online object query. We introduce the notion of a distilled set, which is a clean, ...
    • Interactive Dimensioning of Parametric Models 

      Kelly, Tom; Wonka, Peter; Müller, Pascal (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We propose a solution for the dimensioning of parametric and procedural models. Dimensioning has long been a staple of technical drawings, and we present the first solution for interactive dimensioning: a dimension line ...
    • Parallel, Realistic and Controllable Terrain Synthesis 

      Gain, James; Merry, Bruce; Marais, Patrick (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      The challenge in terrain synthesis for virtual environments is to provide a combination of precise user control over landscape form, with interactive response and visually realistic results. We present a system that builds ...
    • Jointly Optimized Regressors for Image Super-resolution 

      Dai, Dengxin; Timofte, Radu; Gool, Luc Van (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Learning regressors from low-resolution patches to high-resolution patches has shown promising results for image super-resolution. We observe that some regressors are better at dealing with certain cases, and others with ...
    • Designing Camera Networks by Convex Quadratic Programming 

      Ghanem, Bernard; Cao, Yuanhao; Wonka, Peter (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      In this paper, we study the problem of automatic camera placement for computer graphics and computer vision applications. We extend the problem formulations of previous work by proposing a novel way to incorporate visibility ...
    • High-Order Recursive Filtering of Non-Uniformly Sampled Signals for Image and Video Processing 

      Gastal, Eduardo S. L.; Oliveira, Manuel M. (The Eurographics Association and John Wiley & Sons Ltd., 2015)
