Multiscale NMF based on intra-pixel and inter-pixel structure adjustment for spectral unmixing

Various improved nonnegative matrix factorization (NMF) methods have been widely used in spectral unmixing (SU), including nonlinear versions to counter for the lower spatial resolution and interaction between materials. But the obtained abundances are still not satisfactory, especially in the bound...
