A Steered-Response Power Algorithm Employing Hierarchical Search for Acoustic Source Localization Using Microphone Arrays
Leonardo O. Nunes,Wallace A. Martins,Markus V. S. Lima,Luiz W. P. Biscainho,Mauricio do V. M. da Costa,Felipe M. Goncalves,Amir Said,Bowon Lee +7 more
TL;DR: This paper proposes a new method for sound source localization (called H-SRP), which applies the SRP approach to space regions instead of grid points, and attains high performance with manageable complexity.
Journal ArticleDOI
Robust Acoustic Self-Localization of Mobile Devices
Diego B. Haddad,Wallace A. Martins,Mauricio do V. M. da Costa,Luiz W. P. Biscainho,Leonardo O. Nunes,Bowon Lee +5 more
TL;DR: This work proposes a set of algorithms that enable a mobile device to passively determine its position relative to a known reference with centimeter precision, based exclusively on the capture of acoustic signals emitted by controlled sources around it.

A Volumetric SRP with Refinement Step for Sound Source Localization
Markus V. S. Lima,Wallace A. Martins,Leonardo O. Nunes,Luiz W. P. Biscainho,Tadeu N. Ferreira,Mauricio do V. M. da Costa,Bowon Lee +6 more
TL;DR: In this paper, a refined volumetric SRP (RV-SRP) was proposed to reduce the computational complexity without sacrificing the accuracy of location estimates, and a refinement step improved on the compromise between complexity and accuracy.

Efficient Steered-Response Power Methods for Sound Source Localization Using Microphone Arrays
Markus V. S. Lima,Wallace A. Martins,Leonardo O. Nunes,Luiz W. P. Biscainho,Tadeu N. Ferreira,Mauricio do V. M. da Costa,Bowon Lee +6 more
TL;DR: This letter proposes an efficient method based on the steered-response power (SRP) technique for sound source localization using microphone arrays: the refined volumetric SRP (RV-SRP), which achieves a significant reduction of the computational complexity without sacrificing the accuracy of location estimates.
