摘要：
The standard matched subspace detector is modified by replacing a full-rank oblique pseudo-inverse with a reduced-dimension version that trades bias for variance. Minimization of the bias squared plus variance produces an order determination rule relating signal to noise ratio and noise gain. The reduced dimension detector is then applied to several detection tasks in hyperspectral imagery yielding promising results.
