    摘要: There are provided an apparatus and a method for establishing a contention window in a WiMedia wireless network. The contention window establishing apparatus includes: a parsing unit extracting the number of devices that intend to transmit data from a beacon received during a beacon period and an access category (AC) of each device; a calculation unit calculating a transmission probability of each access category (AC) on the basis of the extracted number of devices; and a contention window establishing unit establishing a contention window for each access category (AC) on the basis of the calculated transmission probability, to reduce contentions among the devices and decrease data transmission latency time, thereby maximizing efficiency in data transmission latency time.

    摘要: A dynamic range enhancement method and apparatus for an imaging device expands a dynamic range of an input image without an associated increase in the amount of image calculations. The dynamic range enhancement method includes producing brightness information and color information from an input image; applying gamma correction and inverse gamma correction to the brightness information to produce a gamma corrected image and an inverse gamma corrected image; comparing variances of the gamma corrected image and the inverse gamma corrected image at identical spots; and expanding a dynamic range of the input image by selecting one of the variances at each spot. The dynamic range of an input image is expanded by applying a post imaging process without increasing calculation amount of the imaging device.

    摘要: A block-based object counting apparatus and a block-based object counting that improves the counting of objects by using a camera. The object counting apparatus includes: a camera acquiring an image; a storage unit for storing average sizes and error data of an object in units of image blocks; and a control unit having a data inputter for receiving the acquired image for input, an object size determinator for determining appearance of the object by comparing a current image with a previous image and then determining the size of the object, a block determinator for determining a block where the object is located, and a counter for counting the object and fixing the counting of the object by comparing the size and location data of the object with data stored in a storage unit.
