Abstract
(EN)
Method, apparatus, computer program product and computer readable medium are disclosed for biometric recognition. The method may comprise obtaining first biometric data, wherein the first biometric data is captured in first condition or non-first condition; determining, by a discriminative network of generative adversarial networks, whether the first biometric data is captured in the first condition or non-first condition; in response to a determination that the first biometric data is captured in the non-first condition, inputting the first biometric data to a generative network of the generative adversarial networks to generate a second biometric data; obtaining a matching result by inputting the first biometric data in response to a determination that the first biometric data is captured in the first condition or the second biometric data to a matching network; and determining a recognition result based on the matching result.

L'invention concerne un procédé, un appareil, un produit de programme informatique et un support lisible par ordinateur destinés à la reconnaissance biométrique. Le procédé consiste à : obtenir des premières données biométriques, les premières données biométriques étant capturées sous une première condition ou non ; faire déterminer, par un réseau discriminatif de réseaux antagonistes génératifs, si les premières données biométriques sont capturées sous la première condition ou non ; en réponse à la détermination selon laquelle les premières données biométriques sont capturées autrement que sous la première condition, introduire les premières données biométriques dans un réseau génératif des réseaux antagonistes génératifs afin de générer des secondes données biométriques ; obtenir un résultat de mise en correspondance en introduisant les premières données biométriques en réponse à la détermination selon laquelle les premières données biométriques sont capturées sous la première condition, ou les secondes données biométriques, dans un réseau de mise en correspondance ; et déterminer un résultat de reconnaissance sur la base du résultat de mise en correspondance.
