Abstract:
1. A pattern recognition system comprising: a) at least one capture device configured to acquire at least one sample, each of said at least one sample associated with a sample identifier; b) a basis configured to encode at least one of said at least one sample, said basis derived using a multitude of representative training samples; c) at least one feature extractor configured to generate at least one signature from at least one of said at least one sample using said basis; d) a gallery, said gallery including at least one gallery sample, each of said at least one gallery sample being one of said at least one signature; e) a rejection threshold, said rejection threshold created using a rejection threshold learning mechanism, said rejection threshold learning mechanism configured to calculate said rejection threshold using at least one of said at least one sample by: f) a storage mechanism configured to store at least one of said at least one gallery sample; and g) an open set recognition stage configured to authenticate or reject as unknown the identity of at least one unknown sample, by:
