Coding Depth through Mask Structure
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We present a coded-aperture method based on a family of masks obtained as the convolution of one "hole" with a structural component consisting of an arrangement of Dirac delta functions. We call the arrangement of delta ... -
Repetition Maximization based Texture Rectification
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Many photographs are taken in perspective. Techniques for rectifying resulting perspective distortions typically rely on the existence of parallel lines in the scene. In scenarios where such parallel lines are hard to ... -
Practical Spectral Photography
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We introduce a low-cost and compact spectral imaging camera design based on unmodified consumer cameras and a custom camera objective. The device can be used in a high-resolution configuration that measures the spectrum ... -
3D Material Style Transfer
(The Eurographics Association and John Wiley and Sons Ltd., 2012)This work proposes a technique to transfer the material style or mood from a guide source such as an image or video onto a target 3D scene. It formulates the problem as a combinatorial optimization of assigning discrete ... -
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 ... -
Procedural Texture Preview
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Procedural textures usually require spending time testing parameters to realize the diversity of appearances. This paper introduces the idea of a procedural texture preview: A single static image summarizing in a limited ... -
Rasterized Bounding Volume Hierarchies
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We present the rasterized bounding volume hierarchy (RBVH), a compact data structure that accelerates approximate ray casting of complex meshes and provides adjustable level of detail. During construction, we identify ... -
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, ... -
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 ... -
Black is Green: Adaptive Color Transformation For Reduced Ink Usage
(The Eurographics Association and John Wiley and Sons Ltd., 2012)A vast majority of color transformations applied to an image in the digital press industry are static and precalculated. In order to achieve the best quality on a wide variety of different images, these transformations ... -
Real-time Realistic Rendering and Lighting of Forests
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Realistic real-time rendering and lighting of forests is an important aspect for simulators and video games. This is a difficult problem, due to the massive amount of geometry: aerial forest views display millions of trees ... -
SMAA: Enhanced Subpixel Morphological Antialiasing
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We present a new image-based, post-processing antialiasing technique, which offers practical solutions to the common, open problems of existing filter-based real-time antialiasing algorithms. Some of the new features include ... -
SimpleFlow: A Non-iterative, Sublinear Optical Flow Algorithm
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Optical flow is a critical component of video editing applications, e.g. for tasks such as object tracking, segmentation, and selection. In this paper, we propose an optical flow algorithm called SimpleFlow whose running ... -
Analytic Anti-Aliasing of Linear Functions on Polytopes
(The Eurographics Association and John Wiley and Sons Ltd., 2012)This paper presents an analytic formulation for anti-aliased sampling of 2D polygons and 3D polyhedra. Our framework allows the exact evaluation of the convolution integral with a linear function defined on the polytopes. ... -
Novel-View Synthesis of Outdoor Sport Events Using an Adaptive View-Dependent Geometry
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We propose a novel fully automatic method for novel-viewpoint synthesis. Our method robustly handles multicamera setups featuring wide-baselines in an uncontrolled environment. In a first step, robust and sparse point ... -
Data Driven Surface Reflectance from Sparse and Irregular Samples
(The Eurographics Association and John Wiley and Sons Ltd., 2012)In recent years, measuring surface reflectance has become an established method for high quality renderings. In this context, especially non-parametric representations got a lot of attention as they allow for a very accurate ... -
Unstructured Light Fields
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We present a system for interactively acquiring and rendering light fields using a hand-held commodity camera. The main challenge we address is assisting a user in achieving good coverage of the 4D domain despite the ... -
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 ... -
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 ... -
Real-Time Disparity Map-Based Pictorial Depth Cue Enhancement
(The Eurographics Association and John Wiley and Sons Ltd., 2012)The availability of stereoscopic image material is increasing rapidly. In contrast to the generation of distance information, displaying it is still a challenging task. To overcome the need for special 3D display hardware, ...
