Perceptual Depth Compression for Stereo Applications
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Conventional depth video compression uses video codecs designed for color images. Given the performance of current encoding standards, this solution seems efficient. However, such an approach suffers from many issues ... -
Analogy-Driven 3D Style Transfer
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Style transfer aims to apply the style of an exemplar model to a target one, while retaining the target s structure. The main challenge in this process is to algorithmically distinguish style from structure, a high-level, ... -
Light Montage for Perceptual Image Enhancement
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Recent photography techniques such as sculpting with light show great potential in compositing beautiful images from fixed-viewpoint photos under multiple illuminations. The process relies heavily on the artists experience ... -
SimSelect: Similarity-based Selection for 3D Surfaces
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Surface selection is one of the fundamental interactions in shape modeling. In the case of complex models, this task is often tedious for at least two reasons: firstly the local geometry of a given region may be hard to ... -
Self-similarity for Accurate Compression of Point Sampled Surfaces
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Most surfaces, be it from a fine-art artifact or a mechanical object, are characterized by a strong self-similarity. This property finds its source in the natural structures of objects but also in the fabrication processes: ... -
Compressing Dynamic Meshes with Geometric Laplacians
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper addresses the problem of representing dynamic 3D meshes in a compact way, so that they can be stored and transmitted efficiently. We focus on sequences of triangle meshes with shared connectivity, avoiding the ... -
3D Timeline: Reverse Engineering of a Part-based Provenance from Consecutive 3D Models
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a novel tool for reverse engineering of modeling histories from consecutive 3D files based on a timeline abstraction. Although a timeline interface is commonly used in 3D modeling packages for animations, it has ... -
ShapeSynth: Parameterizing Model Collections for Coupled Shape Exploration and Synthesis
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Recent advances in modeling tools enable non-expert users to synthesize novel shapes by assembling parts extracted from model databases. A major challenge for these tools is to provide users with relevant parts, which is ... -
Recurring Part Arrangements in Shape Collections
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Extracting semantically related parts across models remains challenging, especially without supervision. The common approach is to co-analyze a model collection, while assuming the existence of descriptive geometric features ... -
On-the-fly Generation and Rendering of Infinite Cities on the GPU
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper, we present a new approach for shape-grammar-based generation and rendering of huge cities in real-time on the graphics processing unit (GPU). Traditional approaches rely on evaluating a shape grammar and ... -
Game Level Layout from Design Specification
(The Eurographics Association and John Wiley and Sons Ltd., 2014)The design of video game environments, or levels, aims to control gameplay by steering the player through a sequence of designer-controlled steps, while simultaneously providing a visually engaging experience. Traditionally ... -
SAFE: Structure-aware Facade Editing
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Many man-made objects, in particular building facades, exhibit dominant structural relations such as symmetry and regularity. When editing these shapes, a common objective is to preserve these relations. However, often ... -
Parallel Generation of Architecture on the GPU
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper, we present a novel approach for the parallel evaluation of procedural shape grammars on the graphics processing unit (GPU). Unlike previous approaches that are either limited in the kind of shapes they allow, ... -
Optimizing Stereo-to-Multiview Conversion for Autostereoscopic Displays
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a novel stereo-to-multiview video conversion method for glasses-free multiview displays. Different from previous stereo-to-multiview approaches, our mapping algorithm utilizes the limited depth range of ... -
Manipulating Refractive and Reflective Binocular Disparity
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Presenting stereoscopic content on 3D displays is a challenging task, usually requiring manual adjustments. A number of techniques have been developed to aid this process, but they account for binocular disparity of surfaces ... -
Panorama Light-Field Imaging
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a novel approach to recording and computing panorama light fields. In contrast to previous methods that estimate panorama light fields from focal stacks or naive multi-perspective image stitching, our approach ... -
Coded Exposure HDR Light-Field Video Recording
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Capturing exposure sequences to compute high dynamic range (HDR) images causes motion blur in cases of camera movement. This also applies to light-field cameras: frames rendered from multiple blurred HDR lightfield ... -
Detection and Reconstruction of Freeform Sweeps
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We study the difficult problem of deciding if parts of a freeform surface can be generated, or approximately generated, by the motion of a planar profile through space. While this task is basic for understanding the geometry ... -
Object Detection and Classification from Large-Scale Cluttered Indoor Scans
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a method to automatically segment indoor scenes by detecting repeated objects. Our algorithm scales to datasets with 198 million points and does not require any training data. We propose a trivially parallelizable ... -
Spatio-Temporal Geometry Fusion for Multiple Hybrid Cameras using Moving Least Squares Surfaces
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Multi-view reconstruction aims at computing the geometry of a scene observed by a set of cameras. Accurate 3D reconstruction of dynamic scenes is a key component for a large variety of applications, ranging from special ...
