Since a fisheye lens can capture a wide angle scenery, it is broadly used for surveillance or outdoor sports. However, acquired images suffer from severe geometric distortions. Most of the existing distortion correction algorithms depend on linear features: images of linear features are...

In this paper, a novel approach is presented for intrusion detection in the field of wide-area outdoor surveillance such as construction site monitoring, using a rotatable stereo camera system combined with a multi-pose object segmentation process. In many current surveillance applications, ...

We propose a novel approach that enables a comparative visual exploration of the transport variability in ensembles of 2D flow fields. To reveal when and where divergences in transport occur, we first present a new approach to analyze the time-varying pairwise dissimilarities of en...

The Metropolis Light Transport algorithm generates physically based images with superior image quality than classical ray tracing. Although it is trivially parallelizable on GPUs by running N MLTs, the performance on current graphics hardware is below par. One of the main problems is&#x...
