Abstract: Disclosed is a device and method for inferring a correlation between objects through image recognition. The device for inferring a correlation between objects through image recognition according to an embodiment comprises a communicator and an interaction inferencer configured to select a main object interacting with a target object at a predetermined distance in the input image or generate a social graph including the main object and the target object.

Abstract: A kiosk for providing a recommendation service according to an embodiment displays an orderer's past ordered product as a recommended product on the screen of the kiosk, the past ordered product read based on a similarity calculation result between a current input attribute representing a contextual feature of a current order status and a past input attribute stored in memory.

Abstract: Exemplary embodiments relate to a method for unlocking a mobile device using authentication based on ear recognition including obtaining an image of a target showing at least part of the target's body in a lock state, extracting a set of ear features of the target from the image of the target, when the image of the target includes at least part of the target's ear, and determining if the extracted set of ear features of the target satisfies a preset condition, and a mobile device performing the same.

Abstract: Embodiments relate to a user authentication device configured to detect a face region in a target object image including at least part of a face of a target object, recognize masked or unmasked in the face region, extract target object characteristics data from the face region of the target object image, call reference data and authenticate if the target object is a registered device user based on the called reference data and the target object characteristics data. The reference data is generated from an unmasked image of the registered device user.
