  • Apparatus and method for generating facial animation
    Patent number: 8624901
    Abstract: An apparatus and method for generating an animation of a virtual character using video data and a limited number of three-dimensional (3D) key models of a virtual character, are provided. The video data includes a sequence of two-dimensional image frames. The key models are blended together using the calculated weights, and a 3D facial expression most similar to the 2D facial expression included in each image frame may be generated. When the above operations are performed for input video data including a sequence of image frames, a facial animation, which makes facial expressions according to facial expressions included in the video data may be created.

  • NETWORK BRIDGE DEVICE AND BUS RESET CONTROL METHOD THEREOF
    Publication number: 20090024774
    Abstract: A network bridge device for controlling IEEE 1394 bus reset includes an interface for receiving information relating to devices belonging to a foreign cluster, from the foreign cluster; and a controller for determining whether to reset a bus of a local cluster by comparing the received information with pre-stored information. Accordingly, the bus reset storming between the clusters can be prevented by selectively executing the bus reset of the cluster.
