Experimental comparison of particle filtering algorithms for acoustic source localization in a reverberant room
Traditional acoustic source localization techniques attempt to determine the current location of an acoustic source from data obtained at an array of sensors during the current time only. Recently, state-space methods have been proposed that use particle filters to perform recursive estimation of the current source location using all previous data. In this paper we present an overview of these ...
متن کاملAcoustic Source Localization in a Heterogeneous Network
I present a potential design of a heterogeneous acoustic sensing network comprised of the Acoustic Embedded Networked Sensing Box (ENSBox) and the Berkeley Mica2 platforms. I also present one potential method of leveraging the presence of Mica2 motes to improve acoustic source localization. More specifically, I present a method of rejecting grating lobes, which may be present in direction-ofarr...
متن کاملCombination of Beamforming and Synchronization Methods for Epileptic Source Localization, using Simulated EEG Signals
Localization of sources in patients with focal seizure has recently attracted many attentions. In the severe cases of focal seizure, there is a possibility of doing neurosurgery operation to remove the defected tissue. The prosperity of this heavy operation completely depends on the accuracy of source localization. To increase this accuracy, this paper presents a new weighted beamforming method...
متن کاملTDOA denoising for acoustic source localization
In this manuscript, we formulate the problem of denoising Time Differences of Arrival (TDOAs) in the TDOA space, i.e. the Euclidean space spanned by TDOA measurements. The method consists of pre-processing the TDOAs with the purpose of reducing the measurement noise. The complete set of TDOAs (i.e., TDOAs computed at all microphone pairs) is known to form a redundant set, which lies on a linear...
متن کاملRandomized group testing for acoustic source localization
Undersea localization requires a computationally expensive partial differential equation simulation to test each candidate hypothesis location via matched filter. We propose a method of batch testing that effectively yields a test sequence output of random combinations of location-specific matched filter correlations, such that the computational run time varies with the number of tests instead ...
