Spectral unmixing is one of the important techniques of hyperspectral imagery processing.Traditional spectral unmixing method based on linear spectral mixing modeling(LSMM) is solved in terms of iteration manner,which suffers a heavy computational burden.In this case,a geometric solving method is proposed for LSMM instead of the iteration manner.Additionally,fixed number and fixed shape of endmembers are used in LSMM,leading to a discount unmixing accuracy.Aiming at this problem and constructing a new spect...
