BIOMETRICS AUTHENTICATION BASED ON A NORMALIZED IMAGE OF AN OBJECT

A method for carrying out a biometrics authentication includes detecting an object from a first image including the object, detecting feature points of the object in the detected object, generating a second image based on the feature points, wherein the second image is a normalized image of the obje...

Zusammenfassung:A method for carrying out a biometrics authentication includes detecting an object from a first image including the object, detecting feature points of the object in the detected object, generating a second image based on the feature points, wherein the second image is a normalized image of the object that is obtained by rotating and resizing the object in the first image, determining whether or not the object in the second image faces front, calculating a feature value of the object upon determining that the object in the normalized image faces front, and comparing the calculated feature value with a reference feature value for the biometrics authentication.
