Figure 5From: Percussive/harmonic sound separation by non-negative matrix factorization with smoothness/sparseness constraintsOptimization of (a) the smoothness and (b) sparseness parameters. (a) Smoothness parameters KTSM and KSSM using the values β=1.5, KTSP=KSSP=0.1 and R p =R h =150 components in the development database E; (b) sparseness parameters KTSP and KSSP using the values β=1.5, KTSM=KSSM=0.1 and R p =R h =150 components in the development database E.Back to article page
