Fig. 3

Ground truth synthetic data when SNR = 30 and the different unmixed concentrations obtained with different algorithms. The three rows correspond to two target fluorescence endmembers: AF488 and AF594, and the background AF. a Ground truth of fluorescence concentrations for simulated AF488, AF594 and AF. The different unmixed abundances of AF488, AF594 and AF obtained with: b MCR-ALS, c NMF\({{l}_{1}}\), d NMFsc, e sNMF, f thNMF
