A fast one-pass-training feature selection technique for GMM-based acoustic event detection with audio-visual data
(2010)
Text en actes de congrés
Accés obertAcoustic event detection becomes a difficult task, even for a small number of events, in scenarios where events are produced rather spontaneously and often overlap in time. In this work, we aim to improve the detection ... -
A hierarchical architecture with feature selection for audio segmentation in a broadcast news domain
(2010)
Text en actes de congrés
Accés obertThis work presents a hierarchical HMM-based audio segmentation system with feature selection designed for the Albayzin 2010 Evaluations. We propose an architecture that combines the outputs of individual binary detectors ... -
A multilingual corpus for rich audio-visual scene description in a meeting-room environment
(ACM Press. Association for Computing Machinery, 2011)
Text en actes de congrés
Accés restringit per política de l'editorialIn this paper, we present a multilingual database specifically designed to develop technologies for rich audio-visual scene description in meeting-room environments. Part of that database includes the already existing ... -
Acoustic event detection based on feature-level fusion of audio and video modalities
(HINDAWI, 2011-03-15)
Article
Accés obertAcoustic event detection (AED) aims at determining the identity of sounds and their temporal position in audio signals. When applied to spontaneously generated acoustic events, AED based only on audio information shows a ... -
Albayzin-2010 audio segmentation evaluation: evaluation setup and results
(2010)
Text en actes de congrés
Accés obertIn this paper, we present the audio segmentation task from the Albayzín-2010 evaluation, and the results obtained by the eight participants from Spanish and Portuguese universities. The evaluation task consisted of the ... -
Audio segmentation of broadcast news : a hierarchical system with feature selection for the Albayzin-2010 evaluation
(IEEE Press. Institute of Electrical and Electronics Engineers, 2011)
Comunicació de congrés
Accés restringit per política de l'editorialIn this paper, we present an audio segmentation system for broadcast news, and its results in the Albayzin-2010 evaluation. First of all, the Albayzin-2010 evaluation setup, developed by the authors, is presented; in ... -
Audio segmentation of broadcast news in the Albayzin-2010 evaluation: overview, results, and discussion
(HINDAWI, 2011-06-17)
Article
Accés obertRecently, audio segmentation has attracted research interest because of its usefulness in several applications like audio indexing and retrieval, subtitling, monitoring of acoustic scenes, etc. Moreover, a previous audio ... -
Audiovisual event detection towards scene understanding
(Institute of Electrical and Electronics Engineers (IEEE), 2009)
Text en actes de congrés
Accés restringit per política de l'editorialAcoustic events produced in meeting environments may contain useful information for perceptually aware interfaces and multimodal behavior analysis. In this paper, a system to detect and recognize these events from a ... -
Detection of overlapped acoustic events using fusion of audio and video modalities
(2010)
Text en actes de congrés
Accés obertAcoustic event detection (AED) may help to describe acoustic scenes, and also contribute to improve the robustness of speech technologies. Even if the number of considered events is not large, that detection becomes a ... -
Feature selection for multimodal: acoustic event detection
(Universitat Politècnica de Catalunya, 2011-07-08)
Tesi
Accés obertThe detection of the Acoustic Events (AEs) naturally produced in a meeting room may help to describe the human and social activity. The automatic description of interactions between humans and environment can be useful for ... -
Improving detection of acoustic events using audiovisual data and feature level fusion
(2009)
Text en actes de congrés
Accés obertThe detection of the acoustic events (AEs) that are naturally produced in a meeting room may help to describe the human and social activity that takes place in it. When applied to spontaneous recordings, the detection ... -
Inclusion of video information for detection of acoustic events using the fuzzy integral
(2008-01-01)
Article
Accés obertWhen applied to interactive seminars, the detection of acoustic events from only audio information shows a large amount of errors, which are mostly due to the temporal overlaps of sounds. Video signals may be a useful ... -
On building and evaluating a broadcast-news audio segmentation system
(2011)
Text en actes de congrés

Source ambiguity resolution of overlapped sounds in a multi-microphone room environment
(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 ... -
Two-source acoustic event detection and localization: online implementation in a smart-room
(2011)
Comunicació de congrés
Accés obertReal-time processing is a requirement for many practical signal processing applications. In this work we implemented online 2-source acoustic event detection and localization algorithms in a Smart-room, a closed space ...
