Embodiment Construction
[0046] figure 1 The main steps of the vertex component analysis algorithm (VCA) to complete the decomposition of hyperspectral image mixed pixels are given:
[0047] 1) It is known that the observed spectrum matrix R=[r 1 , r 2 ,...,r N ], N is the number of pixels in the image, first use the singular value decomposition (SVD) to reduce the dimension of the observed spectral matrix, and transform it into the q-dimensional subspace, see the following formula
[0048] X = U q T R - - - ( 1 )
[0049] Among them, U q is a matrix consisting of the first q vectors of the left transformation matrix of SVD.
[0050] 2) Project X onto the hyperplane to obtain monomer S q :
[0051] [ Y ] : , j ...
