TRex: A Tomography Reconstruction Proximal Framework for Robust Sparse View X-Ray Applications.
TL;DR: This work provides an overview and performs an experimental comparison between the famous iterative reconstruction methods in terms of reconstruction quality in sparse view situations, and derives the proximal operators for the four best methods.

Defocus Techniques For Camera Dynamic Range Expansion
TL;DR: The results show that while combining state-of-the-art aperture filters and deconvolution methods can reduce the dynamic range of the defocused image, providing higher image quality than previous methods, rarely does the loss in image fidelity justify the improvements in dynamic range.
Proceedings ArticleDOI
Light field optical flow for refractive surface reconstruction
TL;DR: In this article, a method to reconstruct a transparent flow surface from a single camera shot with the aid of a Micro-lens array is discussed, where an intentionally prepared high frequency background which is placed behind the refractive flow is captured and a curl-free optical flow algorithm is applied between pairs of images taken by different micro-lenses.

Wand zur Absorption der Sonnenstrahlen
TL;DR: In this paper, a Wand mit oder aus einer auf der Ausenseite davor etwa parallel befestigten, den Sonnestrahlen ausgesetzten Schicht, insbesondere einervorgehangten Fassade zur Absorption der Sonnenstrahlungsenergie.
Illuminating Micro Geometry Based on Precomputed Visibility
TL;DR: In this article, an inexpensive method for consistently illuminating height fields and bump maps, as well as simulating BRDFs based on precomputed visibility information is presented. But this method does not consider the effects of shadowing effects, and even indirect illumination caused by scattered light.
