New Appearance Models for Natural Image Matting
Image matting is the task of estimating a fore- and background layer from a single image. To solve this ill posed problem, an accurate modeling of the scene’s appearance is ne...

Similarity Metrics and Efficient Optimization for Simultaneous Registration
We address the alignment of a group of images with simultaneous registration. Therefore, we provide further insights into a recently introduced class of multivariate similarity ...

Color Estimation from a Single Surface Color
This paper estimates illumination colors by using only a single surface color taken under multiple illumination colors. Past researchers have found that there is a difficulty in ...

Maximizing Intra-individual Correlations for Face Recognition Across Pose Differences
The variations of pose lead to significant performance decline in face recognition systems, which is a bottleneck in face recognition. A key problem is how to measure the simila...

Illumination and Spatially Varying Specular Reflectance from a Single View
Estimating the illumination and the reflectance properties of an object surface from a sparse set of images is an important but inherently ill-posed problem. The problem becomes...

Relighting Objects from Image Collections
We present an approach for recovering the reflectance of a static scene with known geometry from a collection of images taken under distant, unknown illumination. In con- trast ...

Physics-based Edge Evaluation for Improved Color Constancy
Edge-based color constancy makes use of image derivatives to estimate the illuminant. However, different edge types exist in real-world images such as shadow, geometry, material...

Dictionary-Free Categorization of Very Similar Objects via Stacked Evidence Trees
Current work in object categorization discriminates among objects that typically possess gross differences which are readily apparent. However, many applications require making ...

Real-Time O(1) Bilateral Filtering
We propose a new bilateral filtering algorithm with computational complexity invariant to filter kernel size, socalled O(1) or constant time in the literature. By showing that a...

Polarization: Beneficial for Visibility Enhancement?
When imaging in scattering media there is a need to enhance visibility. Some approaches have used polarized images in this context with apparent success. These methods take adva...
