A method and apparatus for applying gradient edge detection to detect features in a biometric, such as a fingerprint, based on data representing an image of at least a portion of the biometric. The image is modeled as a function of the features. Data representing an image of the biometric is acquired, and features of the biometric are modeled for at least two resolutions. The method and apparatus improves analysis of both high-resolution images of biometrics of friction ridge containing skin that include resolved pores and lower resolution images of biometrics without resolved pores.

L'invention concerne un procédé et un appareil d'application d'une détection de bore de gradient permettant de détecter les caractéristiques d'une image biométrique, notamment d'une empreinte digitale, d'après les données représentant une image d'au moins une partie de l'image biométrique. L'image est modélisée comme fonction des caractéristiques. Les données représentant une image biométrique sont acquises et les caractéristiques de l'image biométrique sont modélisées pour au moins deux résolutions. Le procédé et l'appareil améliorent l'analyse des images haute résolution en biométrie de la peau présentant des crêtes papillaires comprenant des pores résolus et des images à résolution plus faible de biométrie sans pores résolus.
