A method for partial fingerprint recognition, the method comprising the steps of extracting features including ridge orientations, valley images, minutiae, and pores from at least two fingerprint fragments, aligning the fingerprint fragments, matching the pores and minutiae on the fingerprint fragments after applying estimated alignment transformation, calculating a final matching score based on a pore matching score and a minutiae matching score, identifying a person based on a result of the final matching score.

Partial fingerprint recognition

A biometric identification system () for identifying a person, the system () comprising: an image acquisition module () to capture a three-dimensional (3D) image of a palm of the person; a region of interest (ROI) extraction module () to extract a 3D subimage from the captured image; and a 3D features extraction module () to extract 3D palmprint features from the 3D subimage; wherein the extracted 3D palmprint features are compared to reference 3D palmprint features to verify the identity of the person.

Method and system for personal identification using 3D palmprint imaging

A method of personal identification includes switching between visible and near infrared light, acquiring palmprint image and palm vein image from a person under the visible and the near infrared light, extracting sub-images from the palmprint image and the palm vein image based on a region of interest, extracting multiple features from the sub-images, and matching the extracted multiple features with stored information in a database to authenticate the person.

Method and apparatus for personal identification using palmprint and palm vein

A method of biometrics identification includes obtaining an image including a portion of a hand of an individual, analyzing the image to find one or more feature parameters defining different characteristics of the hand, and comparing the feature parameters with reference information in a database. The features parameters including a geometrical features parameter, a palm line features parameter or a palm texture features parameter.
