Multi-Illuminant Dataset
Color constancy algorithms under non-uniform illumination are particularly hard to evaluate. Ground truth illumination measurements are either inaccurate or only sparsely set in the scene. We provide a dataset of four scenes, captured under combinations of 6 spectral filters. After the capturing, the scenes were painted gray and recaptured. This protocol provides pixel-wise ground truth, but […]Color constancy algorithms under non-uniform illumination are particularly hard to evaluate.

Digital Brain Perfusion Phantom
The Digital Brain Perfusion Phantom package provides data and Matlab tools to create a realistic digital 4D brain phantom, in particular for reproducible evaluation of reconstruction algorithms using non-linear regularization for perfusion CT and perfusion C-arm CT. It is based on the Realistic Digital Brain Perfusion Phantom originally published by Riordan et al. Since classical […]

DaLiAc – Daily Life Activities Datasets
Various approaches for movement analysis have been proposed in literature. Up to date, it is not clear which solution is outperforming the others. The provision of benchmark datasets are mandatory for research groups. This could enhance and speed up the process of getting the best performing and most appropriate algorithm for movement analysis. Currently, in […]

Carotid Artery TOF MRA Data Set (PASCAL)
The segmentation of the carotid bifurcation region in non contrast-enhanced MRA TOF datasets is challenging due to its susceptibility to irregular blood flow patterns. These lead to intensity deviations especially close to the bifurcation and even to signal voids. We provide here standardized MRA TOF datasets of this region along with manual segmentations to be used […]

Computational Two-Illuminant Datasets
Obtaining quantitative ground truth for color constancy under multiple light sources is difficult. We provide two datasets of 58 and 20 images that are exposed to two illuminants. The ground truth is obtained from an algorithm that operates on multiple aligned input images. Read more & download

André Aichert
Epipolar Consistency in Transmission Imaging Two X-ray projection images of a rigid object may have different points of view, yet redundant information can be identified in such images. Not unlike a checksum, these occur naturally in the data and are known as consistency conditions. Real acquisitions, however, result from a measurement process which is affected […]
