An Efficient Demosaicing Technique using Geometrical Information

Color image sensors use color filter arrays (CFA) to capture information at each sensor pixel position and require color demosaicing to reconstruct full color images. The quality of the demosaicked image is hindered by the sensor characteristics during the ...

Talbot images of wavelength-scale amplitude gratings

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

By means of experiment and simulation, we achieve unprecedented insights into the formation of Talbot images to be observed in transmission for light diffracted at wavelength-scale amplitude gratings. Emphasis is put on disclosing the impact and the interp ...

Tracking the US business cycle with a singular spectrum analysis

In this paper we resort to singular spectrum analysis to disentangle the US GDP into several underlying components of interest. The business cycle indicator yielded through this method is shown to bear a resemblance with band-pass filtered output, and our ...

Nanocomposite Coatings for Solar Energy Conversion: Large Opportunities for Small Structures

Andreas Schueler

Due to their fascinating optical and electronical properties, nanometer-scaled structures play an important role in solar energy conversion [1]. Nanocomposite coatings consist typically of dielectric, semiconducting or metallic nanocrystals embedded in a h ...

Correlation-based Joint Acquisition and Demosaicing of Visible and Near-Infrared Images

Sabine Süsstrunk, Yue Lu, Zahra Sadeghipoor Kermani

Joint processing of visible (RGB) and near-infrared (NIR) images has recently found some appealing applications, which make joint capturing a pair of visible and NIR images an important problem. In this paper, we propose a new method to design color filter ...

Plasmon induced transparency in cascaded pi-shaped metamaterials

Hatice Altug, Arif Engin Cetin

We experimentally and numerically demonstrate a planar metamaterial consisting of two asymmetrically positioned pi-structures in a single unit that exhibits plasmonic analogue of electromagnetically induced transparency (EIT). Through the coupling of the c ...

High-speed internal strain measurements in composite structures under dynamic load using embedded FBG sensors

John Botsis, Joël Cugnoni, Dragan Coric, Jeannot Frieden

Internal strain measurements in cross-ply carbon-epoxy composite plates under dynamic loads are carried out using embedded FBG sensors. The principle of the FBG interrogation is based on intensity demodulation achieved via a Fabry-Perot filter. To account ...

Monolithic Silicon Chip for Immunofluorescence Detection on Single Magnetic Beads

Edoardo Charbon, Martinus Gijs, Ulrike Lehmann, Caroline Vandevyver, Emile Dupont

While fluorescence detection is widely used for bioassays owing to its high sensitivity, a complete fluorescent microscopy setup, comprised of a light source, optical filters, a microscope body, and a camera, still is bulky equipment, compromising its use ...

Online Piece-wise Linear Approximation of Numerical Streams with Precision Guarantees

Willy Zwaenepoel, Emmanuel Cecchet

Continuous "always-on" monitoring is beneficial for a number of applications, but potentially imposes a high load in terms of communication, storage and power consumption when a large number of variables need to be monitored. We introduce two new filtering ...

Using Digital Cameras as Quasi-Spectral Radiometers to Study Complex Fenestration Systems

Marilyne Andersen

This work discusses the use of digital cameras fitted with absorption filters as quasi-spectral radiometers. By filtering incident light into selected wavelength intervals, accurate estimates of radiances can be made for unknown spectra. This approach is b ...
