Results of the prototype camera for FACT

Werner Lustermann, Mathieu Ribordy, Thomas Günther Bretz

The maximization of the photon detection efficiency (PDE) is a key issue in the development of cameras for Imaging Atmospheric Cherenkov Telescopes. Geiger-mode Avalanche Photodiodes (G-APD) are a promising candidate to replace the commonly used photomulti ...

A 99 Dollar Head-Mounted Eye Tracker

Pierre Dillenbourg, Frédéric Kaplan, Andrea Mazzei, Youri Marko

Head-mounted eye-trackers are powerful research tools to study attention processes in various contexts. Most existing commercial solutions are still very expensive, limiting the current use of this technology. We present a hardware design to build, at low ...

Controlling spectral response of photodetector for an image sensor

Edoardo Charbon, Cristiano Niclass

A method for controlling the spectral response of light sensitive semiconductor elements in an array (8) using an electric control signal (Vop) applied to said semiconductor elements. The light sensitive semiconductor elements could be a single photon aval ...

Registration for Super-Resolution: Theory, Algorithms, and Applications in Image and Mobile Video Enhancement

Martin Vetterli, Luciano Sbaiz, Patrick Vandewalle

The relation between sensor resolution and the optics of a digital camera is determined by the Nyquist sampling theorem: the sampling frequency should be larger than twice the maximum frequency of the image content coming out of the optical system. If a lo ...

A Unified Calibration Approach For Generic Cameras

The classic perspective projection is mostly used when calibrating a camera. Although this approach is fairly developed and often suitable, it is not necessarily adequate to model any camera system like fish-eyes or catadioptrics. The perspective projectio ...

Mobile Cosmetics Advisor: An Imaging Based Mobile Service

Sabine Süsstrunk, Joanna Marguier

Selecting cosmetics requires visual information and often benefits from the assessments of a cosmetics expert. In this paper we present a unique mobile imaging application that enables women to use their cell phones to get immediate expert advice when sele ...

Image-Based Mobile Service: Automatic Text Extraction and Translation

Jérôme Berclaz

We present a new mobile service for the translation of text from images taken by consumer-grade cell-phone cameras. Such capability represents a new paradigm for users where a simple image provides the basis for a service. The ubiquity and ease of use of c ...

Single-Photon Synchronous Detection

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

Phase and intensity of light are detected simultaneously using a fully digital imaging technique: single-photon synchronous detection. This approach has been theoretically and experimentally investigated in this paper. We designed a fully integrated camera ...

Virtual View Generation with a Hybrid Camera Array

Engin Tola, Zeyu Zhang

Virtual view synthesis from an array of cameras has been an essential element of three-dimensional video broadcasting/conferencing. In this paper, we propose a scheme based on a hybrid camera array consisting of four regular video cameras and one time-of-f ...

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 ...
