Factored Facade Acquisition using Symmetric Line Arrangements
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We introduce a novel framework for image-based 3D reconstruction of urban buildings based on symmetry priors. Starting from image-level edges, we generate a sparse and approximate set of consistent 3D lines. These lines ... -
Fast Grasp Synthesis for Various Shaped Objects
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Human-like grasp planning is difficult because a human hand has a high number of degrees of freedom, and there are many grasping styles depending on the shape of an object and purpose. We propose a fast grasp synthesis ... -
Generalized Swept Mid-structure for Polygonal Models
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We introduce a novel mid-structure called the generalized swept mid-structure (GSM) of a closed polygonal shape, and a framework to compute it. The GSM contains both curve and surface elements and has consistent sheet-by-sheet ... -
A GPU-based Approach for Massive Model Rendering with Frame-to-Frame Coherence
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Rendering massive 3D models in real-time has long been recognized as a very challenging problem because of the limited computational power and memory space available in a workstation. Most existing rendering techniques, ... -
How Not to Be Seen -- Object Removal from Videos of Crowded Scenes
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Removing dynamic objects from videos is an extremely challenging problem that even visual effects professionals often solve with time-consuming manual frame-by-frame editing. We propose a new approach to video completion ... -
Importance Caching for Complex Illumination
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Realistic rendering requires computing the global illumination in the scene, and Monte Carlo integration is the best-known method for doing that. The key to good performance is to carefully select the costly integration ... -
Interaction Retrieval by Spacetime Proximity Graphs
(The Eurographics Association and John Wiley and Sons Ltd., 2012)In this paper, we propose a new method to index and retrieve animation scenes in which multiple characters closely interact with one another. Such a technique can be an important tool for animators when they want to ... -
Interactive Coherence-Based Façade Modeling
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We propose a novel interactive framework for modeling building façades from images. Our method is based on the notion of coherence-based editing which allows exploiting partial symmetries across the façade at any level of ... -
Interactive Editing of GigaSample Terrain Fields
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Previous terrain rendering approaches have addressed the aspect of data compression and fast decoding for rendering, but applications where the terrain is repeatedly modified and needs to be buffered on disk have not been ... -
Interactive Multi-perspective Imagery from Photos and Videos
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Photographs usually show a scene from a single perspective. However, as commonly seen in art, scenes and objects can be visualized from multiple perspectives. Making such images manually is time consuming and tedious. We ... -
Interactive Self-Organizing Windows
(The Eurographics Association and John Wiley and Sons Ltd., 2012)In this paper, we present the design and implementation of a dynamic window management technique that changes the perception of windows as fixed-sized rectangles. The primary goal of self-organizing windows is to automatically ... -
Iterative Image Warping
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Animated image sequences often exhibit a large amount of inter-frame coherence which standard rendering algorithms and pipelines are ill-equipped to exploit, limiting their efficiency. To address this inefficiency we ... -
Light-Field Retargeting
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We present a first approach to light-field retargeting using z-stack seam carving, which allows light-field compression and extension while retaining angular consistency. Our algorithm first converts an input light field ... -
Linear Analysis of Nonlinear Constraints for Interactive Geometric Modeling
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Thanks to its flexibility and power to handle even complex geometric relations, 3D geometric modeling with nonlinear constraints is an attractive extension of traditional shape editing approaches. However, existing approaches ... -
Manipulation of Flexible Objects by Geodesic Control
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We propose an effective and intuitive method for controlling flexible models such as ropes and cloth. Automating manipulation of such flexible objects is not an easy task due to the high dimensionality of the objects and ... -
Manufacturing Layered Attenuators for Multiple Prescribed Shadow Images
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We present a practical and inexpensive method for creating physical objects that cast different color shadow images when illuminated by prescribed lighting configurations. The input to our system is a number of lighting ... -
Medial Kernels
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We introduce the medial kernel, an association measure which provides for a robust construction of volume-aware distances defined directly on point clouds. The medial kernel is a similarity measure defined as the likelihood ... -
Mesh Colorization
(The Eurographics Association and John Wiley and Sons Ltd., 2012)This paper proposes a novel algorithm for colorization of meshes. This is important for applications in which the model needs to be colored by just a handful of colors or when no relevant image exists for texturing the ... -
Metering for Exposure Stacks
(The Eurographics Association and John Wiley and Sons Ltd., 2012)When creating a High-Dynamic-Range (HDR) image from a sequence of differently exposed Low-Dynamic-Range (LDR) images, the set of LDR images is usually generated by sampling the space of exposure times with a geometric ... -
Multitouch Gestures for Constrained Transformation of 3D Objects
(The Eurographics Association and John Wiley and Sons Ltd., 2012)3D transformation widgets allow constrained manipulations of 3D objects and are commonly used in many 3D applications for fine-grained manipulations. Since traditional transformation widgets have been mainly designed for ...
