Here, we investigate PVT solutions based on multi-constellation receivers and dedicated augmentation networks allowing to determine the track on which a train is operating with a very high safety Integrity level. Because the time needed to accomplish

In this paper we propose a segmentation method aimed at separating the moving objects from the background in a generic video sequence. This task, accomplished at the coder site, is intended to support some new functionalities oriented to access and d

In this paper we extend a segmentation method aimed at separating the moving objects from the background in a generic video sequence by means of an Higher Order Statistics (HOS) significance test performed on a group of inter-frame differences. The t

The objective of a sound event detector is to recognize anomalies in an audio clip and return their onset and offset. However, detecting sound events in noisy environments is a challenging task. This is due to the fact that in a real audio signal sev

The European train control system employs GSM-R for communications between trains and the command/control centers. GSM-R technology is quite old and will be replaced in the near future by other technologies offering less expensive solutions, especial
Preliminary design and characterization of a low-cost and low-power visible light positioning system
Designs and results for a low-power and economical fingerprint visible light positioning (VLP) system are discussed in this paper. A system using four white LEDs and one photodiode was deployed. The LEDs are independently controlled and modulated by

At the start of missions trains compliant with the European ERTMS/ETCS standard have to run in Staff Responsible Mode (SRM) until the track where the train is lying on is identified by the Control Center (i.e., the Radio Block Center). Since SRM impl

Recent years have seen the rapid spread of biometric technologies for automatic people recognition. However, security and privacy issues still represent the main obstacles for the deployment of biometric-based authentication systems. In this paper, w
