    • closedAccess   Fast and Reliable Noise Estimation for Hyperspectral Subspace Identification 

      Benner, Peter; Novaković, Vedran; Plaza, Antonio; Quintana-Orti, Enrique S. Institute of Electrical and Electronics Engineers (IEEE) (2015-02)
      In this letter, we introduce an efficient algorithm to estimate the noise correlation matrix in the initial stage of the hyperspectral signal identification by minimum error (HySime) method, commonly used for signal subspace ...

    • openAccess   Noise estimation for hyperspectral subspace identification on FPGAs 

      León, Germán; González, Carlos; Mayo, Rafael; Mozos, Daniel; Quintana-Orti, Enrique S. Springer (2019-05)
      We present a reliable and efficient FPGA implementation of a procedure for the computation of the noise estimation matrix, a key stage for subspace identification of hyperspectral images. Our hardware realization is based ...
