Abstract:
A person recognizing apparatus, comprising:a feature pattern extracting device which extracts a feature pattern obtainable from at least one person to be recognized; a recognition information calculating device which calculates recognition information containing at least one subspace corresponding to each of said at least one person to be recognized, from a calculation amount extracted by said feature pattern extracting device; a registered information holding device which holds recognition information corresponding to each of said at least one person to be recognized by said recognition information calculating device, as registered recognition information, or holds updating recognition information; a recognizing device which recognizes the person by using recognition information calculated by said recognition information calculating device or a feature pattern extracted by said feature pattern extracting device and the registered recognition information held in said registered information holding device; and a registered information updating device which updates the registered recognition information held in said registered information holding device by using at least one of first, second, and third updating methods, said first updating method being to update the subspace included in said registered recognition information corresponding to each of said at least one person to be recognized by use of the recognition information calculated by said recognition information calculating device or the feature pattern extracted by said feature pattern extracting device, said second updating method being to combine a new subspace with the subspace by use of the recognition information and the feature pattern, and said third updating method being to add a subspace having been used in the recognition.
