MPEG-7 sound-recognition tools
نویسنده
چکیده
The MPEG-7 sound-recognition Descriptors and Description Schemes consist of tools for indexing audio media using probabilistic sound models. The Descriptors provide containers for category labels, as well as data structures for quantitative information about sound content. We describe the normative tools, as well as informative methods, for automatic description extraction and sound matching.

Results: It was investigated the effect of the temporal zero cross...
متن کاملMusical Applications of MPEG-7 Audio
the MPEG-7 international standard contains new tools for computing similarity and classification of audio clips and for extracting prominent acoustic features from mixed audio scenes. Among the applications for the standardized tools are enhanced software tools for composition and sound editing. In this paper we present these tools and discuss possible directions for future applications.
متن کاملKDD-Based Approach to Musical Instrument Sound Recognition
Automatic content extraction from multimedia files is a hot topic nowadays. Moving Picture Experts Group develops MPEG-7 standard, which aims to define a unified interface for multimedia content description, including audio data. Audio description in MPEG-7 comprises features that can be useful for any content-based search of sound files. In this paper, we investigate how to optimize sound repr...
متن کاملGeneral sound classification and similarity in MPEG-7
We introduce a system for generalised sound classification and similarity using a machine-learning framework. Applications of the system include automatic classification of environmental sounds, musical instruments, music genre and human speakers. In addition to classification, the system may also be used for computing similarity metrics between a target sound and other sounds in a database. We...
متن کاملA multidomain approach for automatic home environmental sound classification
This article presents a multidomain approach which addresses the problem of automatic home environmental sound recognition. The proposed system will be part of a human activity monitoring system which will be based on heterogeneous sensors. This work concerns the audio classification component and its primary role is to detect anomalous sound events. We compare the discriminative capabilities o...
