Natural Image Colorization
(The Eurographics Association, 2007)In this paper, we present an interactive system for users to easily colorize the natural images of complex scenes. In our system, colorization procedure is explicitly separated into two stages: Color labeling and Color ... -
Near Optimal Hierarchical Culling: Performance Driven Use of Hardware Occlusion Queries
(The Eurographics Association, 2006)The most efficient general occlusion culling techniques are based on hardware accelerated occlusion queries. Although in many cases these techniques can considerably improve performance, they may still reduce efficiency ... -
A New Reconstruction Filter for Undersampled Light Fields
(The Eurographics Association, 2003)This paper builds on previous research in the light field area of image-based rendering. We present a new reconstruction filter that significantly reduces the "ghosting" artifacts seen in undersampled light fields, while ... -
A New Ward BRDF Model with Bounded Albedo
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Due to its realistic appearance, computational convenience, and efficient Monte Carlo sampling, Ward s anisotropic BRDF is widely used in computer graphics for modeling specular reflection. Incorporating the criticism that ... -
Non-linear Volume Photon Mapping
(The Eurographics Association, 2005)This paper describes a novel extension of the photon mapping algorithm, capable of handling both volume multiple inelastic scattering and curved light paths simultaneously. The extension is based on the Full Radiative ... -
A Novel Hemispherical Basis for Accurate and Efficient Rendering
(The Eurographics Association, 2004)This paper presents a new set of hemispherical basis functions dedicated to hemispherical data representation. These functions are derived from associated Legendre polynomials. We demonstrate the usefulness of this basis ... -
A Novel Method for Fast and High-Quality Rendering of Hair
(The Eurographics Association, 2006)This paper proposes a new rendering approach for hair. The model we use incorporates semantics-related information directly in the appearance modeling function which we call a Semantics-Aware Texture Function (SATF). This ... -
On Floating-Point Normal Vectors
(The Eurographics Association and Blackwell Publishing Ltd, 2010)In this paper we analyze normal vector representations. We derive the error of the most widely used representation, namely 3D floating-point normal vectors. Based on this analysis, we show that, in theory, the discretization ... -
On the Effective Dimension of Light Transport
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Light transport is often characterized within a high-dimensional space although practitioners have long known that it commonly behaves as a much lower-dimensional phenomenon. We study the effective dimension of light ... -
Online Construction of Surface Light Fields
(The Eurographics Association, 2005)We present a system for interactively capturing, constructing, and rendering surface light fields by incrementally building a low rank approximation to the surface light field. Each image is incorporated into the lighting ... -
Opacity Shadow Maps
(The Eurographics Association, 2001)Opacity shadow maps approximate light transmittance inside a complex volume with a set of planar opacity maps. A volume made of standard primitives (points, lines, and polygons) is sliced and rendered with graphics hardware ... -
Optimizing Color Matching in a Lighting Reproduction System for Complex Subject and Illuminant Spectra
(The Eurographics Association, 2003)This paper presents a technique for improving color matching results in an LED-based lighting reproduction system for complex light source spectra. In our technique, we use measurements of the spectral response curve of ... -
An Optimizing Compiler for Automatic Shader Bounding

Optimizing Disparity for Motion in Depth
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Beyond the careful design of stereo acquisition equipment and rendering algorithms, disparity post-processing has recently received much attention, where one of the key tasks is to compress the originally large disparity ... -
Optimizing Environment Maps for Material Depiction
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present an automated system for optimizing and synthesizing environment maps that enhance the appearance of materials in a scene. We first identify a set of lighting design principles for material depiction. Each principle ... -
Out of Core Photon-Mapping for Large Buildings
(The Eurographics Association, 2005)This paper describes a new scheme for computing out-of-core global illumination in complex indoor scenes using a photon-mapping approach. Our method makes use of a cells-and-portals representation of the environment for ... -
Packet-based Hierarchal Soft Shadow Mapping
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Recent soft shadow mapping techniques based on back-projection can render high quality soft shadows in real time. However, real time high quality rendering of large penumbrae is still challenging, especially when multilayer ... -
Painting With Texture
(The Eurographics Association, 2006)We present an interactive texture painting system that allows the user to author digital images by painting with a palette of input textures. At the core of our system is an interactive texture synthesis algorithm that ... -
Parameterization-Aware MIP-Mapping
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present a method of generating mipmaps that takes into account the distortions due to the parameterization of a surface. Existing algorithms for generating mipmaps assume that the texture is isometrically mapped to the ... -
Patch-based Texture Interpolation
(The Eurographics Association and Blackwell Publishing Ltd, 2010)In this paper, we present a novel exemplar-based technique for the interpolation between two textures that combines patch-based and statistical approaches. Motivated by the notion of texture as a largely local phenomenon, ...
