Abstract:
본 발명은 응답 속도를 개선한 내용 기반의 영상 크기 조절 방법 및 장치에 관한 것으로, 더욱 상세하게는 영상을 이루는 각 픽셀들의 중요도를 계산하여 최대한 콘텐츠를 유지한 상태로 영상의 크기를 변경하는 심카빙(Seam Carving) 방식을 이용한 영상 크기 조절 방법에 있어서, 영상을 소정 영역으로 분할한 후 각각의 영역에서 에너지값 및 심(Seam)을 계산하여 이를 서로 비교하도록 함으로써 연산 알고리즘의 계산 복잡도를 줄여 하드웨어 자원의 부하를 감소시키고, 전체 영상 영역 대신 분할된 일부 영역에 대해서만 재계산하여 영상의 크기를 조절하도록 함으로써 연산 처리시 필요한 처리 시간을 줄여 응답 속도를 빠르게 하는 효과가 있다.
Abstract:
PURPOSE: An image size control method based on response speed improvement content and apparatus thereof are provided to compare energy values with a core by calculating the core and the energy value in each area. CONSTITUTION: An image area division unit(110) divides the pixel energy map of an input image into one or more areas. An area core extraction unit(150) creates area cores. An area core comparison unit(160) compares the minimum path of the area cores. A core selection unit(170) determines optimized core in order to control the size of the image which includes minimum paths. A control unit(130) controls the size of the image.
Abstract:
A system for providing a game service through NFC(Near Field Communication) is provided to prevent unnecessary memory use and distribute load applied to a host terminal by assigning priority according to order of guest terminals joining in a game, and transceiving data between the host terminal and the guest terminal sequentially according to the priority. An NFC module(201) transceives data with an NFC communicator of guest terminals. A game generator(203) provides a list of games stored in a game database(202) and access/executes game data corresponding to game selection information by a game generation command. A game joining information collector(204) provides game generation information to the neighboring guest terminals through the NFC module, and receives or collects a game joining request from the guest terminals. A priority assigner(205) assigns priority to each guest terminal. A game progress information collector(206) receives or collects game progress information of each guest terminal according to the priority. A game progress manager(207) activates the game by a game execution command, collects/reflects the game progress information to the game, and transmits the game information reflecting the game progress information to the guest terminals.
Abstract:
A time synchronization method for wireless sensor network is provided to reduce a transform time and perform a time synchronization based on a transmission time at a reference transmitter. A time synchronization method for wireless sensor network includes the steps of: transmitting a reference packet for a time synchronization at a reference transmitter(S101), and stores the transmission time of the reference packet at the same time(S103); receiving the reference packet and storing the transmission time of the reference packet at a base station and neighboring nodes(S105); transmitting the stored receiving time of the reference packet at the base station(S107); and after receiving the receiving time of the reference packet transmitted from the base station at the neighboring nodes and the reference transmitter(S109), changing a local time corresponding to the receiving time of the reference packet(S111).
