| Abstract(in English) | Source number plays an important role in blind source separation (BSS) and sound source localization (SSL) based on subspace approach and is used in order to determined the number of separation signals in BSS and the dimension of the signal subspace in SSL. In these fields, it is assumed that source number is given. However, it is impossible to know the number in natural conversations. Recently attention is focused on multi-modal signal processing. Integration between signals received by different sensors, for example an acoustic signal and an image signal, enables to simplify a difficult problem and to improve the performance of the signal processing, compared with single signal processing. This paper proposes multi-modal source number estimation in multi-party conversations by using acoustic and image information. Experiments shows the proposed method outperforms the conventional method. |
