SYSTEM AND METHOD FOR MANAGING DIGITAL CONTENTS

摘要

Disclosed are a system and method for managing digital contents. An exemplary embodiment according to the present invention provides to a system for managing digital contents, including a learning module extracting feature vectors of input digital contents and performing column subspace mapping on the feature vectors to calculate a column subspace projection matrix; an index module using the matrix to perform an index work on the digital contents and then, storing the matrix and the digital contents; and a search module performing the column subspace mapping on the feature vectors of query data when the query data for searching the digital contents are input and searching the digital contents indexed by the matrix having high similarity to the mapped feature vectors of the query data.
