shade.js: Adaptive Material Descriptions
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In computer graphics a material is a visual concept that is parameterizable and should work for arbitrary 3D assets and rendering systems. Since provided parameters and attributes as well as the capabilities of rendering ... -
Single-shot High Dynamic Range Imaging Using Coded Electronic Shutter
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Typical high dynamic range (HDR) imaging approaches based on multiple images have difficulties in handling moving objects and camera shakes, suffering from the ghosting effect and the loss of sharpness in the output HDR ... -
Sky Based Light Metering for High Dynamic Range Images
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Image calibration requires both linearization of pixel values and scaling so that values in the image correspond to real-world luminances. In this paper we focus on the latter and rather than rely on camera characterization, ... -
Sparse Localized Decomposition of Deformation Gradients
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Sparse localized decomposition is a useful technique to extract meaningful deformation components out of a training set of mesh data. However, existing methods cannot capture large rotational motion in the given mesh ... -
Structure Aware Visual Cryptography
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Visual cryptography is an encryption technique that hides a secret image by distributing it between some shared images made up of seemingly random black-and-white pixels. Extended visual cryptography (EVC) goes further in ... -
Sub-Pixel Anti-Aliasing Via Triangle-Based Geometry Reconstruction
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Anti-aliasing has recently been employed as a post-processing step to adapt to the deferred shading technique in real-time applications. Some of these existing algorithms store supersampling geometric information as geometric ... -
Template-Based Sampling of Anisotropic BRDFs
(The Eurographics Association and John Wiley and Sons Ltd., 2014)BRDFs are commonly used to represent given materials' appearance in computer graphics and related fields. Although, in the recent past, BRDFs have been extensively measured, compressed, and fitted by a variety of ana- ... -
Time-Lapse Photometric Stereo and Applications
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper presents a technique to recover geometry from time-lapse sequences of outdoor scenes. We build upon photometric stereo techniques to recover approximate shadowing, shading and normal components allowing us to ... -
Using Physically Based Rendering to Benchmark Structured Light Scanners
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Structured light scanning is ubiquituous in 3D acquisition. It is capable of capturing high geometric detail at a low cost under a variety of challenging scene conditions. Recent methods have demonstrated robustness in the ...
