A Study on Multiple Sound Source Localization using Extended Histogram
Takanori Someya, Kenji Suyama (Tokyo Denki Univ.) EA2008-38
Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a new method for multiple sound source
localization utilizing weighted reliability histogram based on
sparseness of speech signals.

In the propose method, multiple time-frequency region are constructed by
using correlation matrices corresponding to multiple forget factors.

In each time-frequency points on such the regions, the
direction-of-arrival(DOA) of source is estimated by using
the Root-MUSIC method.

Then, the extended histogram is made by weighting the reliability for
each the results.

Finally, the mixed Cauchy distribution is fitted to the histogram
in a criterion of maximum likelihood.

Several experimental results in actual room environment are shown
to present an ability of multiple source localization.
