摘要： An apparatus for recognizing an iris is provided. The apparatus includes an image acquisition module configured to acquire a plurality of images, and a processor configured to select at least one image for iris recognition from among the plurality of images based on pupil information of each of the plurality of images, and recognize an iris in at least one image, wherein the pupil information includes at least one of information about a pupil radius and information about a pupil contrast.

摘要： According to an embodiment of the disclosure, there is provided a biometrics-based user authentication method including: obtaining a user's biometric image, obtaining a shallow biometric feature from the user's biometric image by using a first neutral network of a learning network model, obtaining a deep biometric feature from the user's biometric image by using a second neutral network of the learning network model, determining a similarity between the shallow and deep biometric features and a valid user's biometric features stored in advance, and determining whether the user matches the valid user, based on the determined similarity.

摘要： A user recognition method that uses an iris is provided. The user recognition method includes generating a first mask for blocking a non-iris object area of an iris image, generating a converted iris image, in which the non-iris object area is blocked according to the first mask, generating a second mask for additionally blocking an inconsistent area, in which quantization results of the converted iris image are inconsistent, by adaptively transforming the first mask according to features of the converted iris image, obtaining an iris code by quantizing pixels included in the iris image, obtaining a converted iris code, in which portions corresponding to the non-iris object area and the inconsistent area are blocked, by applying the second mask to the iris code, and recognizing a user by matching a reference iris code, stored by the user in advance, to the converted iris code.
