An apparatus and method for generating synthetic training data for motion recognition. The method includes generating a three-dimensional (3D) human body model in real time according to motion of a human body, converting volume data of the 3D human body model into a 3D linear structure and extracting skeletal joint information, generating a data set of a human body image and skeletal joint information by rendering the 3D human body model and the skeletal joint information, and providing the data set of the image and the skeletal joint information as synthetic training data for motion recognition.

A method of increasing a photographing speed of a photographing device which capture an image through a combination of two or more photographing devices and generate and provide an image by using the captured image, thereby increasing a photographing speed. An RGB image obtaining device and a depth image obtaining device alternately perform photographing to obtain an image. Also, a second depth image and a second RGB image respectively corresponding to a first RGB image and a first depth image which are alternately obtained by performing alternate photographing are synthesized and output, thereby actually increasing a photographing speed by twice.

A hand motion recognizing apparatus obtains an image with first resolution including a hand and an image with second resolution higher than the first resolution including the hand, maps the image with the first resolution and the image with the second resolution, extracts a hand position from the image with the first resolution, obtains a hand region corresponding to the hand position from the image with the second resolution mapped to the image with the first resolution, and subsequently estimates a hand motion from the hand region.

Provided is an apparatus and method for obtaining depth information using an optical pattern. The apparatus for obtaining depth information using the optical pattern may include: a pattern projector to generate the optical pattern using a light source and an optical pattern projection element (OPPE), and to project the optical pattern towards an object area, the OPPE comprising a pattern that includes a plurality of pattern descriptors; an image obtaining unit to obtain an input image by photographing the object area; and a depth information obtaining unit to measure a change in a position of at least one of the plurality of pattern descriptors in the input image, and to obtain depth information of the input image based on the change in the position.

A method for controlling a game character is provided. The method includes analyzing a game situation in which a character appears; and controlling a behavior of the character depending on a result of the analyzing. Accordingly, situation recognition and behavior control depending on the recognized situation are simultaneously performed using the same algorithm, so that the calculation amount can be reduced, and thus high artificial intelligence can be implemented with less computer resources. Also, a game developer does not need to implement individual behavior rules of characters depending on game situations since a situation of the game may be recognized through learning of an artificial neural network using a game database of game situations, and thus the behavior of characters can be controlled depending on the recognized situation.

Method for controlling game character

A database query system is provided. The database cache system includes: a network library which processes an access request issued by the online game server by using an input output completion port (IOCP); at least one database connection module which provides a connector for reading data from the database or recording data to the database; a database cache which stores data read from the database by the database connection module; and at least one cache buffer which is allotted to an IOCP worker thread corresponding to a database query request issued by the online game server and stores data read from the database, which is to be transmitted to the online game server.
