  • Patent number: 11954891
    Abstract: Provided is a method of compressing an occupancy map of a three-dimensional (3D) point cloud, and more specifically, a method of compressing an occupancy map of a point cloud in which an occupancy map image of a point cloud existing in a 3D space is compressed based on a compression quality or a patch-by-patch inspection method of the occupancy map image so that compression distortion is minimized when reconstructing the compressed occupancy map image so as to remarkably improve the quality of a reconstructed occupancy map image.

  • Patent number: 9154218
    Abstract: A method and apparatus establish a connection in a mobile terminal with a device compatible with BLUETOOTH, a short range wireless communications technology at the 2.4 GHz band. If connectable BLUETOOTH devices are detected in the vicinity of the mobile terminal and there is at least one priority-registered BLUETOOTH device among the detected BLUETOOTH devices, the mobile terminal connects with a highest-priority BLUETOOTH device among the detected BLUETOOTH devices. If other connectable BLUETOOTH devices are detected in the vicinity of the mobile terminal while the mobile terminal is connected to a BLUETOOTH device, and there is at least one priority-registered BLUETOOTH device higher in priority than the currently connected BLUETOOTH device, among the detected BLUETOOTH devices, the mobile terminal switches the connection to a highest-priority BLUETOOTH device among the detected BLUETOOTH devices.
