Multi-camera triangulation of feature points based on a minimisation of the overall ℓ 2 reprojection error can get stuck in suboptimal local minima or require slow global op-timisation. For this reason, researchers have proposed op-timising the ℓ ∞ norm of the ℓ 2 single view reprojection errors , which avoids the problem of local minima entirely. In this(More)
In two-view stereo matching, the disparity of occluded pixels cannot accurately be estimated directly: it needs to be inferred through, e.g., regularisation. When capturing scenes using a plenoptic camera or a camera dolly on a track, more than two input images are available, and – contrary to the two-view case – pixels in the central view will only very(More)
In this demonstration, we present a new programming framework, Quasar, for heterogeneous programming on CPU and single/multi-GPU. Our programming framework consists of a high-level language that is aimed at relieving the programmer from hardware-related implementation issues that commonly occur in CPU/GPU programming, allowing the programmer to focus on the(More)
1 ABSTRACT Non-rigid structure-from-motion in an on-line setting holds many promises for useful applications, and off-line reconstruction techniques are already very advanced. Literature has only recently started focusing on on-line reconstruction, with only a handful of existing techniques available. Here we propose a novel method of history representation(More)
