- 27 June 2016
A new energy on the vertices of a regularly sampled spatiotemporal bilateral grid is designed, which can be solved efficiently using a standard graph cut label assignment, and implicitly approximates long-range, spatio-temporal connections between pixels while still containing only a small number of variables and only local graph edges.

- Computer ScienceACM Transactions on Graphics
- 21 July 2013
This paper proposes an algorithm that leverages coherence in massive light fields by breaking with a number of established practices in image-based reconstruction, and introduces a sparse representation and a propagation scheme for reliable depth estimates which make the algorithm particularly effective for 3D input.
Nonlinear disparity mapping for stereoscopic 3D

- Computer ScienceACM Transactions on Graphics
- 26 July 2010
The most important perceptual aspects of stereo vision are discussed and their implications for stereoscopic content creation are formalized into a set of basic disparity mapping operators that enable us to control and retarget the depth of a stereoscopic scene in a nonlinear and locally adaptive fashion.
A system for retargeting of streaming video
- Philipp Krähenbühl, Manuel Lang, Alexander Sorkine-Hornung, M. Gross
- Computer ScienceACM Transactions on Graphics
- 1 December 2009
A novel, integrated system for content-aware video retargeting which combines key frame based constraint editing with numerous automatic algorithms for video analysis and seamlessly integrates into postproduction and computes the reformatting in real-time.
Fully Connected Object Proposals for Video Segmentation
- Federico Perazzi, Oliver Wang, M. Gross, Alexander Sorkine-Hornung
- Computer ScienceIEEE International Conference on Computer Vision
- 7 December 2015
A novel approach to video segmentation using multiple object proposals that combines appearance with long-range point tracks to ensure robustness with respect to fast motion and occlusions over longer video sequences is presented.
High-quality surface splatting on today's GPUs
- M. Botsch, Alexander Sorkine-Hornung, Matthias Zwicker, L. Kobbelt
- Computer ScienceProceedings Eurographics/IEEE VGTC Symposium…
- 21 June 2005
This paper presents an approach that achieves a quality comparable to the original EWA splatting at a rate of more than 20M elliptical splats per second, and provides per-pixel Phong shading even for dynamically changing geometries and high-quality anti-aliased rendering by employing a screen-space pre-filter in addition to the object-space reconstruction filter.
