PoissonNMF is an ImageJ plugin that allows to decompose spectrally resolved fluorescence microscopy data into the contributions of the labels. It can be used without known reference spectra and estimates these spectra using non-negative matrix factorization, suitably modified for shot-noise dominated data. In cases when reference spectra are inaccurately known, the inaccurate spectra can be refined to yield a better decomposition of the data.
