Exploring Material Recognition for Estimating Reflectance and Illumination From a Single Image
(The Eurographics Association, 2016)
In this paper, we propose a novel approach for recovering illumination and reflectance from a single image. Our approach relies on the assumption that the surface geometry has already been reconstructed and a-priori knowledge ...
Filtering Distributions of Normals for Shading Antialiasing
(The Eurographics Association, 2016)
High-frequency illumination effects, such as highly glossy highlights on curved surfaces, are challenging to render in a stable manner. Such features can be much smaller than the area of a pixel and carry a high amount of ...
Using Flash Photography and Image-Based Rendering to Document Cultural Heritage Artifacts
(The Eurographics Association, 2016)
A novel image-based rendering system is proposed for documenting cultural heritage artifacts. The system utilizes backscattering photography to acquire the initial pictures and derives estimates for the object's diffuse ...
Weathering of Urban Scenes: Challenges and Possible Solutions
(The Eurographics Association, 2016)
In this paper, we propose to discuss on one of the main challenges in realistic rendering of urban scenes: changes in appearance over time within a urban context. After studying the previous work on weathering techniques, ...
Practical Experiences with Using Autocollimator for Surface Reflectance Measurement
(The Eurographics Association, 2016)
We present our experiences with using an autocollimator to set up the surface reflectance measurement for both BRDF and BTF. Assuming the measured material appearance is put on a locally flat surface, the autocollimator ...
Color Restoration of Scanned Archaeological Artifacts with Repetitive Patterns
(The Eurographics Association, 2016)
Our work addresses the problem of virtually restoring archaeological artifacts. Virtual restoration is the process of creating a noise-free model of a degraded object, to visualize its original appearance. Our work focuses ...
