Informatikkolloquium (vcg) mit Prof. Dr. Dirk Arnold
Prof. Dr. Dirk Arnold von der kanadischen Partneruniversität Dalhousie University in Halifax hält am 30. Juni 2011 einen Vortrag im Rahmen des Informatikkolloquiums der Visual Computing Group (vcg) am Fachbereich Informatik der Hochschule Bonn-Rhein-Sieg.
Thema: Making Waves: Research in Dalhousie's Graphics and Visualisation Lab
wann: Donnerstag, 30. Juni 2011, 16:30 Uhr
Wo: C 116, Campus Sankt Augustin
Abstract:
This talk presents three recent or ongoing research projects undertaken in Dalhousie University's Graphics and Visualisation Lab: 1) Multi-band Fourier synthesis of ocean waves allows the realistic animation of the ocean surface in real time. A wide range of wave numbers can be modelled at a small fraction of the computational costs of the single-band approach, making the algorithm suitable for applications such as computer games and naval and flight simulators. 2) The iterative deconvolution of images is accomplished using a gradient based optimiser that enforces non-negativity constraints in some but not all iterations. As result, better advantage can be taken of unconventional step length settings. 3) Interactive evolution is used as an approach to the tone mapping of high-dynamic range images, making it possible to simultaneously exploit the capabilities of several tone mapping operators without the need for explicitly tuning their parameters.
