WebJun 27, 2014 · In hyperspectral images (HSI), many of the spectral bands have low noise levels (LN bands) while some have high noise levels (junk bands). If a noise reduction algorithm is globally applied to the whole dataset, it usually affects the LN bands adversely. Therefore, we consider different criteria for denoising LN and junk bands. First, we … WebThe spectral unmixing can be divided into linear unmixing (LU) and nonlinear unmixing (NLU) [ 2, 3 ]. LU assumes that photons only interact with one material and there is no interaction between materials. Usually, linear mixing only happens in macro scenarios.
