DOI: 10.1080/01431161.2018.1539270
Abstract: ABSTRACT Spectral mixture analysis (SMA) has been widely applied for estimating fractional land-cover types from remote sensing pixels. SMA typically assumes each spectral band has equal contribution to the unmixing results, which has attracted debates… read more here.
