Fig. 4From: NMF-weighted SRP for multi-speaker direction of arrival estimation: robustness to spatial aliasing while exploiting sparsity in the atom-time domainHistogram of SRP-NMF (CNMF) on a mixture of 3 sources taken from the SiSEC database dev1_male3_liverec_250ms_5cm_mix.wav, with β=60 and DT=35. The ground truth DoAs are 50∘,80∘ and 105∘. The 3 peaks are clearly visible nowBack to article page
