Texture Replacement of Garments in Monocular Video
(The Eurographics Association, 2006)In this paper, we present a video processing algorithm for texture replacement of moving garments in monocular video recordings. We use a color-coded pattern which encodes texture coordinates within a local neighborhood ... -
Feature-Aware Texturing
(The Eurographics Association, 2006)We present a method for inhomogeneous 2D texture mapping guided by a feature mask, that preserves some regions of the image, such as foreground objects or other prominent parts. The method is able to arbitrarily warp a ... -
Texture Transfer Using Geometry Correlation
(The Eurographics Association, 2006)Texture variation on real-world objects often correlates with underlying geometric characteristics and creates a visually rich appearance. We present a technique to transfer such geometry-dependent texture variation from ... -
Silhouette Texture
(The Eurographics Association, 2006)Using coarse meshes with textures and/or normal maps to represent detailed meshes often results in poor visual quality along silhouettes. To tackle this problem, we introduce silhouette texture, a new data structure for ... -
Symmetric Photography: Exploiting Data-sparseness in Reflectance Fields
(The Eurographics Association, 2006)We present a novel technique called symmetric photography to capture real world reflectance fields. The technique models the 8D reflectance field as a transport matrix between the 4D incident light field and the 4D exitant ... -
Spatio-Angular Resolution Tradeoffs in Integral Photography
(The Eurographics Association, 2006)An integral camera samples the 4D light field of a scene within a single photograph. This paper explores the fundamental tradeoff between spatial resolution and angular resolution that is inherent to integral photography. ... -
Surface Enhancement Using Real-time Photometric Stereo and Reflectance Transformation
(The Eurographics Association, 2006)Photometric stereo recovers per-pixel estimates of surface orientation from images of a surface under varying lighting conditions. Transforming reflectance based on recovered normal directions is useful for enhancing the ... -
Real-time Soft Shadow Mapping by Backprojection
(The Eurographics Association, 2006)We present a new real-time soft shadow algorithm using a single shadow map per light source. Therefore, our algorithm is well suited to render both complex and dynamic scenes, and it handles all rasterizable geometries. ... -
Practical, Real-time Studio Matting using Dual Imagers
(The Eurographics Association, 2006)This paper presents a practical system for capturing high-resolution video mattes using cameras that contain two imagers on one optical axis. The dual imagers capture registered frames that differ only by defocus or ... -
Warping and Partitioning for Low Error Shadow Maps
(The Eurographics Association, 2006)We evaluate several shadow map algorithms based on warping and partitioning using the maximum perspective aliasing error over the entire view frustum. With respect to our error metric, we show that a range of warping ... -
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 ... -
Efficient Wavelet Rotation for Environment Map Rendering
(The Eurographics Association, 2006)Real-time shading with environment maps requires the ability to rotate the global lighting to each surface point's local coordinate frame. Although extensive previous work has studied rotation of functions represented by ... -
Relighting Human Locomotion with Flowed Reflectance Fields
(The Eurographics Association, 2006)We present an image-based approach for capturing the appearance of a walking or running person so they can be rendered realistically under variable viewpoint and illumination. In our approach, a person walks on a treadmill ... -
Adaptive Visibility-Driven View Cell Construction
(The Eurographics Association, 2006)We present a new method for the automatic partitioning of view space into a multi-level view cell hierarchy. We use a cost-based model in order to minimize the average rendering time. Unlike previous methods, our model ... -
Wavelet Radiance Transport for Interactive Indirect Lighting
(The Eurographics Association, 2006)Global illumination is a complex all-frequency phenomenon including subtle effects caused by indirect lighting. Computing global illumination interactively for dynamic lighting conditions has many potential applications, ... -
Exploiting Temporal Coherence for Incremental All-Frequency Relighting
(The Eurographics Association, 2006)Precomputed radiance transfer (PRT) enables all-frequency relighting with complex illumination, materials and shadows. To achieve real-time performance, PRT exploits angular coherence in the illumination, and spatial ... -
Instant Ray Tracing: The Bounding Interval Hierarchy
(The Eurographics Association, 2006)We introduce a new ray tracing algorithm that exploits the best of previous methods: Similar to bounding volume hierarchies the memory of the acceleration data structure is linear in the number of objects to be ray traced ... -
Making Radiance and Irradiance Caching Practical: Adaptive Caching and Neighbor Clamping
(The Eurographics Association, 2006)Radiance and irradiance caching are efficient global illumination algorithms based on interpolating indirect illumination from a sparse set of cached values. In this paper we propose an adaptive algorithm for guiding spatial ... -
Sequential Sampling for Dynamic Environment Map Illumination
(The Eurographics Association, 2006)Sampling complex illumination in the form of environment maps has received a lot of attention in computer graphics. Recent work in this area has demonstrated that drawing samples from the product of light and BRDF produces ... -
Real-time Multi-perspective Rendering on Graphics Hardware
(The Eurographics Association, 2006)Multi-perspective rendering has a variety of applications; examples include lens refraction, curved mirror re- flection, caustics, as well depiction and visualization. However, multi-perspective rendering is not yet practical ...
