Fisheye lens correction by estimating 3D location

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...

Robust object detection for video surveillance using stereo vision and Gaussian mixture model

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, ...

Comparative visual analysis of transport variability in flow ensembles

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...

Coherent metropolis light transport on the GPU using speculative mutations

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...
