In this letter, a new geometric matched filter (MF) is proposed by combining the standard MF with concepts of convex geometry. The purpose of the method is twofold: for subpixel target detection and for partial unmixing of a hyperspectral image. In standard matched filtering, the filter is designed based on the background statistics of the entire image,(More)
An important problem in hyperspectral unmixing is solving the inversion problem, which determines the abundances of each endmember in each pixel, taking the constraints on these abundances into account. In this paper, we present a new geometrical method for solving this inversion problem, based on the equivalence with the simplex projection problem, and(More)
