Time–frequency ratio-based blind separation methods for attenuated and time-delayed sources

NMF factor- izes the input matrix comprising non-negative entries as two smaller matrices, and is able to extract the most significant components that explain the observed data, i.e.,

The procedure is a feature- based method able to detect predetermined spectral shape, providing at the same time an estimate of its power level, an estimate of its frequency

13 It may be noted that lower performance is achieved for Set 3 of sources but, again, this corresponds to a more difficult situation than in real applications since: i) the

Most of the recent solutions for blind separation of sources are based on esti- mation of a separation matrix, such that the product of the observation signals (mixtures)
