A Spectral BSSRDF for Shading Human Skin
(The Eurographics Association, 2006)
We present a novel spectral shading model for human skin. Our model accounts for both subsurface and surface scattering, and uses only four parameters to simulate the interaction of light with human skin. The four parameters ...
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 ...
Segmentation-Based 3D Artistic Rendering
(The Eurographics Association, 2006)
This paper introduces segmentation-based 3D non-photorealistic rendering, in which 3D scenes are rendered as a collection of 2D image segments. Segments abstract out unnecessary detail and provide a basis for defining new ...
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 ...
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 ...
Bidirectional Instant Radiosity
(The Eurographics Association, 2006)
This paper presents a new sampling strategy to achieve interactive global illumination on one commodity computer. The goal is to propose an efficient numerical stochastic scheme which can be well adapted to a fast rendering ...
Automatic Multiperspective Images
(The Eurographics Association, 2006)
Multiperspective images generated from a collection of photographs or a videostream can be used to effectively summarize long, roughly planar scenes such as city streets. The final image will span a larger field of view ...
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. ...
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 ...
