Abstract:

Matched filters MFs are easy to make optically but fail to take into account either within-class variations or between-class similarities. We show a general method for taking those effects into account. Because our filter reduces to the MF in a simple-enough case, we call it a generalized matched filter GMF. Because the statistics of the situation govern the GMF, no analytic formula exists and a computer numerical derivation is required. Because the GMF is computer generated, it can not be created by optical means. Instead, it requires a computer generated hologram. Because no adequate computer hologram existed, Aerodyne built such a holowriter.
