Abstract: The present invention relates to a motion recognition method and a motion recognition device; and provides a method for recognizing an actual motion of a user by acquiring information about a motion of a user and performing dynamic time-warping between the information about the motion and preset comparison target information. Accordingly, the motion of the user can be accurately and rapidly recognized.

Abstract: Disclosed is a system for editing a broadcast in real time and an editing method therefor. The method includes receiving a plurality of video streams from a plurality of mobile terminals through a first streaming server; displaying the plurality of video streams being received on a preview area of a display; receiving a first user input for selecting at least one of the plurality of video streams displayed on the preview area; and displaying a user interface for editing a broadcast screen on an editing area of the display; receiving a second user input via the user interface; editing the selected at least one video stream based the first user input and the second user input, thereby generating an edited broadcast video stream; displaying the edited broadcast video stream on a broadcast screen area of the display; and transmitting the edited broadcast video stream to a second streaming server.

Abstract: An embodiment of the present invention enables 2D pointing technology to be used in a 3D space, thereby proving an intuitive 3D user interface. More particularly, an embodiment of the present invention implements an action point that enables an eye and finger of a user and an action point on a screen to be arranged on a rectilinear line, thereby providing an intuitive user interface.

Abstract: The present invention provides a method for stabilizing an instable estimated rotation angle included in motion information generated from a plurality of image frames captured by an NUI device and correcting motion information for a fast speed motion lost during a process of stabilization based on the captured plurality of image frames. Accordingly, an instable motion among motions restored based on motion information can be stabilized, and the accuracy of the motion can be maintained.

Abstract: The present invention relates to a method and system for image synthesis. According to a first aspect of the present invention, an image synthesis system for providing a method for image synthesis may include: a first foreground unit configured to receive a predetermined region that is selected from a source image, including an object, as a first foreground by a user; a similarity determination unit configured to calculate the similarity between each of the first foreground and the background distinct from the first foreground on the source image and each pixel included in the source image; a second foreground unit configured to determine a second foreground, including the remaining pixels excluding pixels, included in each of the first foreground and the background, from the source image, based on the calculated similarity; and an image synthesis unit configured to combine the first foreground and the second foreground with a ground image.
