Fingerprint biometric machine representations based on triangles
First Claim
1. An apparatus for representing biometrics, comprising:
- a biometric feature extractor for extracting features corresponding to a biometric depicted in an image, for defining at least one set of at least one geometric shape by at least some of the features, each of the at least one geometric shape having at least one geometric feature that is invariant with respect to a first set of transforms applied to at least a portion of the image; and
a transformer for applying the first set of transforms to the at least a portion of the image to obtain at least one feature representation that includes at least one of the at least one geometric feature, and for applying a second set of transforms to the at least one feature representation to obtain at least one transformed feature representation.

Abstract
There is provided an apparatus, method, and program storage device for representing biometrics. The apparatus includes a biometric feature extractor and a transformer. The biometric feature extractor is for extracting features corresponding to a biometric depicted in an image, and for defining one or more sets of one or more geometric shapes by one or more of the features. Each of the one or more geometric shapes has one or more geometric features that is invariant with respect to a first set of transforms applied to at least a portion of the image. The transformer is for applying the first set of transforms to the at least a portion of the image to obtain one or more feature representations that include one or more of the one or more geometric features, and for applying a second set of transforms to the one or more feature representations to obtain one or more transformed feature representations.
