Validation of a Polynomial Model for Generic Cameras

This paper discusses practical implementation of a generic camera model for a wide variety of common cameras equipped with catadioptric, fish-eye, short- or long focal length lenses. A unified approach of deriving approximate model parameters followed by a ...

ITER CODAC interface for the visible and infra-red wide angle viewing cameras

Jonathan Bryan Lister

The amount of data generated by the infra-red and visible cameras at ITER is expected to be considerably larger than most diagnostics. ITER will have 12 infra-red cameras plus 12 visible cameras in four different equatorial port plugs. Each of the ports wi ...

Semiconductor Image Sensing

Peter Seitz, Nicolas Blanc

Silicon is an excellent detector material for electromagnetic radiation in the wavelength range of 0.1 to 1000 nm. In the visible spectral range (400-700 nm), external quantum efficiencies approaching 100% are obtained. When combined with the amazing minia ...

Colouring the near infrared

Sabine Süsstrunk

Current digital camera sensors are inherently sensitive to the near-infrared part of the spectrum. To prevent the near-IR contamination of images, an IR blocking filter (hot mirror) is placed in front of the sensor. In this work, we start by replacing the ...

Single-Photon Synchronous Detection

Edoardo Charbon, Ties Jan Henderikus Kluter, Cristiano Niclass, Claudio Favi, Frédéric Monnier

A novel imaging technique is proposed for fully digital detection of phase and intensity of light. A fully integrated camera implementing the new technique was fabricated in a 0.35μm CMOS technology. When coupled to a modulated light source, the camera can ...

MOEMS thermal imaging camera

Muhammed Fatih Toy, Onur Ferhanoglu

A novel thermo-mechanical Infrared (IR) imaging array with integrated diffraction gratings for optical readout was fabricated and tested. Parylene was used as a structural material for its low thermal conductivity and high thermal expansion properties. Tes ...

Object Detection and Matching in a Mixed Network of Fixed and Mobile Cameras

Michel Bierlaire, Pierre Vandergheynst, Murat Kunt, Alexandre Massoud Alahi

This work tackles the challenge of detecting and matching objects in scenes observed simultaneously by fixed and mobile cameras. No calibration between the cameras is needed, and no training data is used. A fully automated system is presented to detect if ...

Tracking the free surface of time-dependent flows: Image processing for the dam-break problem

Christophe Ancey, Steve Cochard

The dam-break problem (i.e., the sudden release of a given volume of fluid down a slope) has attracted a great deal of attention from mechanicians and physicists over the past few years, with particular interest devoted to the free-surface profile and the ...

Understanding Metro Station Usage using Closed Circuit Television Cameras Analysis

Jean-Marc Odobez

In this paper, we propose to show how video data available in standard CCTV transportation systems can represent a useful source of information for transportation infrastructure management, optimization and planning if adequately analyzed (e.g. to facilita ...
