Automatic Camera Control and Directing with an Ultra-High-Definition Collaborative Recording System
Bram Vanherle, Tim Vervoort, Nick Michiels +1
Capturing an event from multiple camera angles can give a viewer the most complete and interesting picture of that event. To be suitable for broadcasting, a human director needs to…
Ray-Based Reflectance Model for Diffraction
Tom Cuypers, Se Baek Oh, Tom Haber +2
We present a novel method of simulating wave effects in graphics using ray--based renderers with a new function: the Wave BSDF (Bidirectional Scattering Distribution Function). Ref…
Full Lensing Analysis of Abell 1703: Comparison of Independent Lens-Modelling Techniques
Adi Zitrin, Tom Broadhurst, Keiichi Umetsu +10
The inner mass-profile of the relaxed cluster Abell 1703 is analysed by two very different strong-lensing techniques applied to deep ACS and WFC3 imaging. Our parametric method has…
Non-parametric strong lens inversion of Cl~0024+1654: illustrating the monopole degeneracy
J. Liesenborgs, S. De Rijcke, H. Dejonghe +1
The cluster lens Cl 0024+1654 is undoubtedly one of the most beautiful examples of strong gravitational lensing, providing five large images of a single source with well-resolved s…
A generalisation of the mass-sheet degeneracy producing ring-like artefacts in the lens mass distribution
J. Liesenborgs, S. De Rijcke, H. Dejonghe +1
The inversion of a gravitational lens system is, as is well known, plagued by the so-called mass-sheet degeneracy: one can always rescale the density distribution of the lens and a…
Non-parametric inversion of gravitational lensing systems with few images using a multi-objective genetic algorithm
J. Liesenborgs, S. De Rijcke, H. Dejonghe +1
Galaxies acting as gravitational lenses are surrounded by, at most, a handful of images. This apparent paucity of information forces one to make the best possible use of what infor…
