Abstract
Configuration is made by a feature pattern extracting section 12 for extracting a feature obtainable from a person, a subspace calculating section 14 for calculating a subspace from the feature pattern, a recognition section 16 for effecting recognition using the subspace, a registered information holding section 18 for holding a plurality of the subspaces, and a registered information updating section 20 for updating the registered information using the subspaces. When identifying a person, the effect of aging change is reduced by suppressing time and year changes and keeping the recognition rate high.
Claims13
A person recognizing apparatus, comprising:
- a feature pattern extracting means for extracting a feature pattern obtainable from a person to be recognized;
- a recognition information calculating means for calculating recognition information containing at least a subspace from the calculation amount extracted by said feature pattern extracting means;
- a registered information holding means for holding multiple recognition information as registered recognition information;
- a recognizing means for recognizing the person by using recognition information calculated by said recognition information calculating means or a feature pattern extracted by said feature pattern extracting means and the registered recognition information held in said registered information holding means;
- a registered information updating means for updating the registered recognition information concerning the person held in said registered information holding means by using the recognition information calculated by said recognition information calculating means or the feature pattern extracted by said feature pattern extracting means.
A person recognizing method comprising:
- a feature pattern extracting step to extract a feature pattern obtainable from a person to be recognized;
- a recognition information calculating step to calculate recognition information containing at least a subspace from the calculation amount extracted by said feature pattern extracting step;
- a registered information holding step to hold multiple recognition information as registered recognition information;
- a recognizing step to recognize the person by using recognition information calculated by said recognition information calculating step or a feature pattern extracted by said feature pattern extracting step and the registered recognition information held in said registered information holding step;
- a registered information updating step to update the registered recognition information concerning the person held in said registered information holding step by using the recognition information calculated by said recognition information calculating step or the feature pattern extracted by said feature pattern extracting step.
A person recognizing program recording means, comprising:
- a feature pattern extracting function for extracting a feature pattern obtainable from a person to be recognized;
- a recognition information calculating function for calculating recognition information containing at least a subspace from the calculation amount extracted by said feature pattern extracting function;
- a registered information holding function for holding multiple recognition information as registered recognition information:
- a recognizing function for recognizing the person by using recognition information calculated by said recognition information calculating function or a feature pattern extracted by said feature pattern extracting function and the registered recognition information held in said registered information holding function;
- a registered information updating function for updating the registered recognition information concerning the person held in said registered information holding function by using the recognition information calculated by said recognition information calculating function or the feature pattern extracted by said feature pattern extracting function.
