Abstract: Provided is a method and system for integrating multiple image markers to generate a single integral image marker for configuring content such as game content. The present invention proposes a method of expressing, in a global coordinate system, feature points for each image marker whose positions are expressed in their local coordinate system by calculating relative positions of the image markers and applying the calculated relative positions to the image makers other than a reference image maker to transform 3D positions of feature points in each image marker.

Abstract: Provided is a user authentication method using a natural gesture input. The user authentication method includes recognizing a plurality of natural gesture inputs from image data of a user, determining number of the plurality of natural gesture inputs as total number of authentication steps, determining a reference ratio representing a ratio of number of authentication steps requiring authentication pass to the total number of the authentication steps, determining an actual ratio representing a ratio of number of authentication steps, where authentication has actually passed, to the total number of the authentication steps, and performing authentication on the user, based on a result obtained by comparing the actual ratio and the reference ratio.
