WebIn the hyperspectral imagery context, the endmember spectra can be identiﬁed as the sources whereas the abundances are the mixing coefﬁcients involved in the PNMM. This paper addresses the problem of supervised nonlinear spectral unmixing of hyperspectral images using PNMMs. Webfor hyperspectral data unmixing, target visualization method to process hyperspectral image, and soil contamination mapping with hyperspectral imagery. This book is a general reference work for students, professional engineers, and readers with interest in the subject. WebThis chapter revisits a well-known fully constrained least squares (FCLS) method developed by Heinz and Chang for linear spectral unmixing. Due to the two physical constraints, abundance sum-to-one constraint (ASC) and abundance non-negativity constraint (ANC), FCLS does not have analytic solutions. how much to ship a 6 pound package
