An Efficient Image Compressor for Charge Coupled Devices Camera

Recently, the discrete wavelet transforms- (DWT-) based compressor, such as JPEG2000 and CCSDS-IDC, is widely seen as the state of the art compression scheme for charge coupled devices (CCD) camera. However, CCD images project on the DWT basis to produce a large number of large amplitude high-frequency coefficients because these images have a large number of complex texture and contour informat...

DE/dx MEASUREMENTS WITH ARGUS

The use of pure heavy hydrocarbons like propane or isobutane has some advantages for drift chaders that measure the specific ionisation for particle identification. With a prototype of the ARGUS drift chamber various gases were tested with a 3 GeV/c electron beam. We found a dE/dx resolution for propane of Fwhm= 10.4% and for isobutane Fwhm = 9.9X, by a factor of + 1.6 better than that for argo...

Crowdsensing Air Quality with Camera-Enabled Mobile Devices

Crowdsensing of air quality is a useful way to improve public awareness and supplement local air quality monitoring data. However, current air quality monitoring approaches are either too sophisticated, costly or bulky to be used effectively by the mass. In this paper, we describe AirTick, a mobile app that can turn any camera enabled smart mobile device into an air quality sensor, thereby enab...

Interaction of Mobile Camera Devices with physical maps

Traditional paper-based maps are still superior to their digital counterparts used on mobile devices in several ways. They provide highresolution, large-scale information with zero power consumption. On the other hand digital maps provide personalized and dynamic information on request, but suffer from small outer scales and low resolutions. In this work we try to combine the advantages of both...
