Differentiable Signed Distance Function Rendering

Wenzel Alban Jakob, Delio Aleardo Vicini, Sébastien Nicolas Speierer

Physically-based differentiable rendering has recently emerged as an attractive new technique for solving inverse problems that recover complete 3D scene representations from images. The inversion of shape parameters is of particular interest but also pose ...

Numerical methods for conservation laws with rough flux

Hakon Andreas Hoel

Finite volume methods are proposed for computing approximate pathwise entropy/kinetic solutions to conservation laws with flux functions driven by low-regularity paths. For a convex flux, it is demonstrated that driving path oscillations may lead to "cance ...

NTIRE 2018 Challenge on Spectral Reconstruction from RGB Images

Lei Zhang, Majed El Helou, Dong Liu, Bing Zhang, Ruofan Zhou, Fayez Lahoud, Marjan Shahpaski

This paper reviews the first challenge on spectral image reconstruction from RGB images, i.e., the recovery of whole-scene hyperspectral (HS) information from a 3- channel RGB image. The challenge was divided into 2 tracks: the “Clean” track sought HS reco ...

A charge carrier transport model for donor-acceptor blend layers

Wolfgang Richard Tress

Highly efficient organic solar cells typically comprise donor-acceptor blend layers facilitating effective splitting of excitons. However, the charge carrier mobility in the blends can be substantially smaller than in neat materials, hampering the device p ...

Image Blending in a High Frame Rate FPGA-based Multi-Camera System

Yusuf Leblebici, Alexandre Schmid, Vladan Popovic, Hossein Afshari, Kerem Seyid, Abdulkadir Akin, Ömer Cogal

Panoptic is a custom spherical light field camera used as a polydioptric system where imagers are distributed over a hemispherical surface, each having its own vision of the surroundings and a distinct focal plane. The spherical light field camera records ...

Practical parallel rendering of detailed neuron simulations

John Anthony Biddiscombe

Parallel rendering of large polygonal models with transparency is challenging due to the need for alpha-correct blending and compositing, which is costly for very large models with high depth complexity and spatial overlap. In this paper we compare the per ...

Real-time Implementation of Gaussian Image Blending in a Spherical Light Field Camera

Yusuf Leblebici, Alexandre Schmid, Vladan Popovic, Hossein Afshari

Panoptic is a custom spherical light field camera used as a polydioptric system where imagers are distributed over a spherical geometry, each having its own vision of the surrounding and a distinct focal plane. The spherical light field camera records ligh ...

On the Bandwidth of the Plenoptic Function

Martin Vetterli, Minh Do

The plenoptic function (POF) provides a powerful conceptual tool for describing a number of problems in image/video processing, vision, and graphics. For example, image based-rendering can be seen as sampling and interpolation of the POF. In such applicati ...

Real-time FPGA implementation of linear blending vision reconstruction algorithm using a spherical light field camera

Yusuf Leblebici, Alexandre Schmid, Vladan Popovic, Hossein Afshari, Abdulkadir Akin

A custom spherical light-field camera used as a polydioptric system where imagers are distributed over a spherical geometry, each having its own vision of the surrounding and distinct focal plane. The spherical light-field camera is also an omnidirectional ...

GUI-Aided NIR and Color Image Blending

Sabine Süsstrunk, Radhakrishna Achanta

A near-infrared (NIR) image of a scene contains different information than the corresponding visible spectrum (RGB) image, due to physical phenomena related to scattering, absorption, and reflectance of the different radiation bands. It can be desirable to ...

Causeway: Support for Controlling and Analyzing the Execution of Web-Accessible Applications

Willy Zwaenepoel

Causeway provides runtime support for the development of distributed meta-applications. These meta-applications control or analyze the behavior of multi-tier distributed applications such as multi-tier web sites or web services. Examples of meta-applicatio ...

Configural and perceptual factors influencing the perception of color transparency

Peggy Gerardin

The mechanisms by which the brain represents colors are largely unknown. In addition, the large number of color phenomena in the natural world has made understanding color rather difficult. Color transparency perception, which is studied in this thesis, is ...
