Spark chambers, scintillation and Cerenkov detectors are used extensively in high energy physics experiments. The potential usefulness of semiconductor detectors is being investigated. There is a need for detectors which will identify very high energy particles. The various types of spark chambers are briefly reviewed, including narrow gap, wide gap and filmless chambers. Applications of scinti...

This paper presents a common framework for subband doubletalk detectors. Within this framework a number of lowcomplexity subband doubletalk detectors are evaluated in comparison with a corresponding fullband detector. The evaluation is performed by using real-data off-line calculations. The evaluation indicates that the subband approach significantly improves the performance.

The evaluation of vision systems is not possible without parameter control as incorrect parameter adjustment can cause performance losses that are more signiicant than the eeect of the component being tested. In this paper we present a model for the contour extraction process and derive from it a method for automatic parameter control. The method works with arbitrary edge detectors, edge types ...

For photoacoustic imaging, usually point-like detectors are used. As a special sensing technology for photoacoustic imaging, integrating detectors have been investigated that integrate the acoustic pressure over an area or line that is larger than the imaged object. Different kinds of optical fiber-based detectors are compared regarding their sensitivity and resolution in three-dimensional phot...

This paper presents a new fusion scheme for enhancing the result quality based on the combination of multiple different detectors. We present a study showing the fusion of multiple video analysis detectors like “detecting unattended luggage” in video sequences. One of the problems is the time jitter between different detectors, i.e. typically one system can trigger an event several seconds befo...
