Acoustic event detection and localization using distributed microphone arrays
Chakraborty, Rupayan (Universitat Politècnica de Catalunya, 2013-12-18)
Tesi
Accés obertAutomatic acoustic scene analysis is a complex task that involves several functionalities: detection (time), localization (space), separation, recognition, etc. This thesis focuses on both acoustic event detection (AED) ... -
Joint model-based recognition and localization of overlapped acoustic events using a set of distributed small microphone arrays
Chakraborty, Rupayan; Nadeu Camprubí, Climent (2017-12-19)
Report de recerca
Accés obertIn the analysis of acoustic scenes, often the occurring sounds have to be detected in time, recognized, and localized in space. Usually, each of these tasks is done separately. In this paper, a model-based approach to ... -
Joint recognition and direction-of-arrival estimation of simultaneous meeting-room acoustic events
Chakraborty, Rupayan; Nadeu Camprubí, Climent (2013)
Text en actes de congrés
Accés restringit per política de l'editorialAcoustic scene analysis usually requires several sub-systems working in parallel for carrying out the various required functionalities. Focusing to a more integrated approach, in this paper we present an attempt to jointly ... -
Model-based processing for acoustic scene analysis
Nadeu Camprubí, Climent; Chakraborty, Rupayan; Wolf, Martin (Institute of Electrical and Electronics Engineers (IEEE), 2014)
Text en actes de congrés
Accés restringit per política de l'editorialThe analysis of acoustic scenes requires several functionalities, being perhaps recognition (speech, speaker, other acoustic events) and spatial localization the two most relevant ones. For a reduced invasiveness, ... -
Real-time multi-microphone recognition of simultaneous sounds in a room environment
Chakraborty, Rupayan; Nadeu Camprubí, Climent (Institute of Electrical and Electronics Engineers (IEEE), 2013)
Text en actes de congrés
Accés restringit per política de l'editorialTime overlapping of acoustic signals, which so often occurs in real life, is a challenge for current state-of-the-art sound recognition systems. In this work, we propose an approach for detecting, identifying and ... -
Sound-model-based acoustic source localization using distributed microphone arrays
Chakraborty, Rupayan; Nadeu Camprubí, Climent (Institute of Electrical and Electronics Engineers (IEEE), 2014)
Text en actes de congrés
Accés restringit per política de l'editorialAcoustic source localization and sound recognition are common acoustic scene analysis tasks that are usually considered separately. In this paper, a new source localization technique is proposed that works jointly with an ... -
Source ambiguity resolution of overlapped sounds in a multi-microphone room environment
Chakraborty, Rupayan; Nadeu Camprubí, Climent; Butko, Taras (2014-04)
Article
Accés obertWhen several acoustic sources are simultaneously active in a meeting room scenario, and both the position of the sources and the identity of the time-overlapped sound classes have been estimated, the problem of assigning ...
