Survivable WDM mesh networks
- Journal of Lightwave Technology
, 1999
"... Abstract—In a wavelength-division-muliplexing (WDM) optical network, the failure of network elements (e.g., fiber links and cross connects) may cause the failure of several optical channels, thereby leading to large data losses. This study examines different approaches to protect a mesh-based WDM op ..."

Index Terms: Audio watermarking, psychoacoustic model
"... In this paper, we present a novel audio watermarking scheme using direct sequence spread spectrum (DSSS) method by which we can embed a text message as a watermark into an audio signal imperceptibly. The watermark embedding and extraction are based on the psychoacoustic model in the frequency domain ..."

Audio thumbnailing of popular music using chroma-based representations
- IEEE Transactions on Multimedia
, 2005
"... Abstract—With the growing prevalence of large databases of multimedia content, methods for facilitating rapid browsing of such databases or the results of a database search are becoming increasingly important. However, these methods are necessarily media dependent. We present a system for producing ..."

of the 12 pitch classes. We evaluate the system on a database of popular music and score its performance against a set of “ideal ” thumbnail locations. Overall performance is found to be quite good, with the majority of errors resulting from songs that do not meet our structural assumptions. Index Terms—Audio
Semantic Indexing of Multimedia Content Using Visual, Audio, and Text Cues
- EURASIP JOURNAL ON APPLIED SIGNAL PROCESSING 2003:2, 170–185
, 2003
"... We present a learning-based approach to the semantic indexing of multimedia content using cues derived from audio, visual, and text features. We approach the problem by developing a set of statistical models for a predefined lexicon. Novel concepts are then mapped in terms of the concepts in the lex ..."

Evaluation of classification techniques for audio indexing
- In proc. 13th Eropean conf. Signal Processing
, 2005
"... This work compares two classification techniques used in audio indexing tasks: Gaussian Mixture Models (GMM) and Support Vector Machines (SVM). GMM is a classical technique taken as reference for comparing the performance of SVM in terms of accuracy and execution time. For testing the methodologies, ..."

State Restoration in Systems of Communicating Processes
- IEEE tinsactions on Pamllel and Distn’buted Systems
, 1980
"... Abstract-In systems of asynchronous processes using messagelists with SEND-RECEIVE primitives for interprocess communication recovery primitives are defined to perform state restoration: MARK saves a particular point in the execution of the program; RESTORE resets the system state to an earlier poin ..."

"... Audio streaming applications have become very popular in recent years owing to their low cost and convenience. However, during network congestions data packets are often delayed or discarded, creating an annoying gap in the streamed media. This paper presents a new approach to audio packet loss conc ..."

Automatic Indexing of Audio 1 Fast Caption Alignment for Automatic Indexing of Audio
"... For large archives of audio media, just as with text archives, indexing is important for allowing quick and accurate searches. Similar to text archives, audio archives can use text for indexing. Generating this text requires using transcripts of the spoken portions of the audio. From them, an alignm ..."

Indexing Spoken Audio By LSA And SOMS
, 2000
"... This paper presents an indexing system for spoken audio documents. The framework is indexing and retrieval of broadcast news. The proposed indexing system applies latent semantic analysis (LSA) and self-organizing maps (SOM) to map the documents into a semantic vector space and to display the semant ..."

Melody transcription from music audio: Approaches and evaluation
- IEEE Transactions on Audio Speech and Language Processing
, 2007
"... Abstract—Although the process of analyzing an audio recording of a music performance is complex and difficult even for a human listener, there are limited forms of information that may be tractably extracted and yet still enable interesting applications. We discuss melody—roughly, the part a listene ..."
