Decentralized CUSUM change detection
(2006)We consider the problem of decentralized change detection using the CUSUM test. More than one sensors acquire independent signals and send their quantized version to a fusion center that uses this information to detect a ... -
Efficient change detection for high dimensional data streams
(2015)The recent technological advancements in cloud computing and the access in increasing computational power has led in undertaking the data processing derived by mobile devices. In particular, when these data are high ... -
A fall detection algorithm for indoor video sequences captured by fish-eye camera
(2015)In this paper we present an algorithm that can discriminate between standing and fallen silhouettes in video sequences acquired by a fish-eye camera, in order to detect falls in an indoor environment. The proposed algorithm ... -
MORFEAS: A non-invasive system for automated sleep apnea detection utilizing snore sound analysis
(2010)Apnea is considered one of the major sleep disorders with great accession in population and significant impact on patient's health. Symptoms include disruption of oxygenation, snoring, choking sensations, apneic episodes, ... -
Multi-microphone fusion for detection of speech and acoustic events in smart spaces
(2014)In this paper, we examine the challenging problem of detecting acoustic events and voice activity in smart indoors environments, equipped with multiple microphones. In particular, we focus on channel combination strategies, ... -
Multi-room speech activity detection using a distributed microphone network in domestic environments
(2015)Domestic environments are particularly challenging for distant speech recognition: reverberation, background noise and interfering sources, as well as the propagation of acoustic events across adjacent rooms, critically ... -
Self-Supervised Soft Obstacle Detection for Safe Navigation of Visually Impaired People
(2021)the context of computer-assisted navigation of visually impaired people (VIP), time-efficient and robust obstacle detection methods are of major importance. Most commonly, obstacle detection algorithms exploit depth ...
