Paraunitary filter banks are important for several signal processing tasks, including coding, multichannel deconvolution and equalization, adaptive beamforming, and subspace processing. In this paper, we consider the task of adapting the impulse response of a multichannel paraunitary filter bank via gradient ascent or descent on a chosen cost function. Our methods are spatio-temporal generaliza...
In this work we have designed a system to play remotely high quality multichannel digital audio by the Power Line home network. POLI-MAS solves the needs imposed by the convergence of the three audio segments, namely, home audio, entertaining audio and PC audio. Thus, the stored audio files in a computer can be played in any location within a home by using the power lines as their transport med...
Multichannel acoustic echo cancellation (MCAEC) is a key technology whenever hands-free and full-duplex communication in modern systems with multichannel sound reproduction is desired. Although the basic principle of echo cancellation has been well known for several decades, the multichannel case poses some additional and fundamentally different challenges. Moreover, there are even some notable...
Multichannel ASR systems commonly separate speech enhancement, including localization, beamforming and postfiltering, from acoustic modeling. In this chapter, we perform multichannel enhancement jointly with acoustic modeling in a deep neural network framework. Inspired by beamforming, which leverages differences in the fine time structure of the signal at different microphones to filter energy...
A report is provided for the ACM SIGKDD community about the 2010 Workshop on Algorithms for Modern Massive Data Sets (MMDS 2010), its origin in MMDS 2006 and MMDS 2008, and future directions for this interdisciplinary research area.
Multimedia Database Systems (MMDS) support rich data types, such as text, images, video, and sound. Queries in MMDSs may refer to the content of the stored multimedia objects. This is called content-based querying. However, manual entry of content descriptions is very difficult and subjective. A better approach is to provide automatic content-based retrieval through image, text, and sound inter...
