Using Morphological Description for Generic Sound Retrieval

by Julien Ricard And , 2003
"... Systems for sound retrieval are usually "sourcecentred ". This means that retrieval is based on using the proper keywords that define or specify a sound source. Although this type of description is of great interest, it is very difficult to implement it into realistic automatic labelling s ..."

Content-based classification, search, and retrieval of audio

by Erling Wold, Thorn Blum, Douglas Keislar, James Wheaton - IEEE Multimedia , 1996
"... say that it belongs to the class of speech sounds or the class of applause sounds, where the system has previously been trained on other sounds in this class. I Acoustical/perceptual features: describing the sounds in terms of commonly understood physical characteristics such as brightness, pitch, a ..."

, and loudness. I Subjective features: describing the sounds using personal descriptive language. This requires training the system (in our case, by example) to understand the meaning of these descriptive terms. For example, a user might be looking for a “shimmering ” sound.

Sound Indexing Using Morphological Description

by unknown authors
"... Abstract—Sound sample indexing usually deals with the recognition of the source/cause that has produced the sound. For abstract sounds, sound-effects, unnatural or synthetic sounds this cause is usually unknown or unrecognizable. An efficient description of these sounds has been proposed by Schaeffe ..."
Abstract - Add to MetaCart
by Schaeffer under the name morphological description. Part of this description consists in describing a sound by identifying the temporal evolution of its acoustic properties to a set of profiles. In this work, we consider three morphological descriptions: dynamic profiles (ascending, descending, ascending

A Technical Description of Atmospheric Sounding by GPS Occultation

by G. A. Hajj, E. R. Kursinski, L. J. Romans, W. I. Bertiger, S. S. Leroy - Journal of Atmospheric and Solar-Terrestrial Physics , 2002
"... In recent years, the Global Positioning System (GPS) has been exploited via radio occultation techniques to obtain profiles of refractivity, temperature, pressure and water vapor in the neutral atmosphere and electron density in the ionosphere. The GPS/MET experiment, which placed a GPS receiver in ..."

in a low-Earth orbit, provided a wealth of data which was used to test this concept and the accuracy of the retrievals. Several investigations have already demonstrated that he retrieval accuracies obtained with GPS/MET is already comparable, if not better, than the more traditional atmospheric sensing

TOWARDS MORPHOLOGICAL SOUND DESCRIPTION USING SEGMENTAL MODELS

by Julien Bloit, Nicolas Rasamimanana, Frederic Bevilacqua
"... We present an approach to model the temporal evolution of audio descriptors using Segmental Models (SMs). This method yields a signal segmentation into a sequence of primitives, constituted by a set of user-defined trajectories. This allows one to consider specific primitive shapes, model their dura ..."

Evaluating Natural Language Processing Systems

by J.R. Galliers, K. Sparck Jones , 1993
"... This report presents a detailed analysis and review of NLP evaluation, in principle and in practice. Part 1 examines evaluation concepts and establishes a framework for NLP system evaluation. This makes use of experience in the related area of information retrieval and the analysis also refers to ev ..."

"... This project generates a vga signal and displays a monochrome bitmap by reading data from SDRAM memory. This project also demonstrates how to mix both VHDL and Verilog code together in the same project. The project uses the vga circuit design provided in Jan Gray’s XSOC project (see references). Bas ..."

). Basically is generates the correct timing signals needed and shifts through a 16-bit word one bit at a time (monochrome) for pixel information. As data is requested, SDRAM memory is accessed and data is retrieved. Accessing SDRAM memory may sound easy, but it’s more complicated than SRAM. XESS has produced

A generic framework for description logics with uncertainty

by Volker Haarslev, Hsueh-ieng Pai, Nematollaah Shiri - in Proceedings of Workshop on Uncertainty Reasoning for the Semantic Web (URSW) at the 4th International Semantic Web Conference (ISWC , 2005
"... Description Logics (DLs) play an important role in the Semantic Web as the foundation of ontology language OWL DL. On the other hand, uncertainty is a form of deficiency or imperfection commonly found in real-world information/data. In this paper, we present a framework for knowledge bases with unce ..."

The Rhythm Transform: Towards A Generic Rhythm Description

by Enric Guaus, Perfecto Herrera - Proc. ICMC; 2005
"... In the past few years, automatic genre classification has become one of the most interesting topics in the Music Information Retrieval (MIR) field. Musical genre is one of the most valuable metadata when managing huge music databases and many successful efforts have been done to automatically comput ..."

compute it. Basically, timbric and rhythmic description of audio is used for this purpose. From our point of view, some of these descriptors have been designed under some rigid constrains and the generalization of these algorithms into more flexible applications becomes a difficult task. In this paper, we

Shape Based Image Retrieval Using Generic Fourier Descriptors

by Dengsheng Zhang, Guojun Lu - Signal Processing: Image Communication 17 , 2002
"... Shape description is one of the key parts of image content description for image retrieval. Most of existing shape descriptors are usually either application dependent or non-robust, making them undesirable for generic shape description. In this paper, a generic Fourier descriptor (GFD) is proposed ..."
