Abstract: A system for generating a multimedia knowledge base uses a multimedia information detection unit to detect texted meta information from multimedia data including at least one combination of a text, a voice, an image and a video and allows a knowledge base shaping unit to use the texted meta information and context information of the multimedia data to divide the multimedia data into syntactic information representing extrinsic configuration information and semantic information representing intrinsic meaning information and may shape the syntactic information and the semantic information into the multimedia knowledge.

Abstract: A domain adaptation-based object recognition apparatus includes a memory configured to store a domain adaptation-based object recognition program and a processor configured to execute the program. The processor learns a generative model for generating a feature or an image similar to a gallery image on the basis of domain adaptation in association with an input probe image and learns an object recognition classification model by using a learning database corresponding to the gallery image and the input probe image, thereby performing object recognition using the input probe image.

Abstract: Smart glasses for selectively tracking a target of visual cognition according to the present invention include a first camera configured to capture a first input image that is a first-person view image of a user, a second camera configured to capture a second input image containing sight line information of the user, a display configured to output additional information corresponding to the first input image, a memory configured to store a program for selectively tracking a target of visual cognition on the basis of the first and second input images, and a processor configured to execute the program stored in the memory, wherein upon executing the program, the processor is configured to detect the target of visual cognition from the first input image and determine, from the second input image, whether the user is in an inattentive state with respect to the target of visual cognition.
