  • Patent number: 11457101
    Abstract: An apparatus for generating broadcast signal frame according to an embodiment of the present invention includes a combiner configured to generate a multiplexed signal by combining a core layer signal and an enhanced layer signal; a power normalizer configured to reduce power of the multiplexed signal to a power level corresponding to the core layer signal; a time interleaver configured to generate a time-interleaved signal by performing time-interleaving that is applied to both the core layer signal and the enhanced layer signal; and a frame builder configured to generate a broadcast signal frame including a preamble for signaling start position information and size information for each of Physical Layer Pipes (PLPs). In this case, the Physical Layer Pipes include a core layer physical layer pipe corresponding to the core layer signal and an enhanced layer physical layer pipe corresponding to the enhanced layer signal.

  • Publication number: 20150172681
    Abstract: The present invention relates to a medical image compression system and method suitable for visually lossless compression and, more specifically, to a medical image compression system and method capable of obtaining medical images at a high enough compression ratio while preventing loss in information needed to diagnose. The medical image compression system according to one example of the present invention comprises: a storage unit for storing initial learning data and an equation regarding an optimal compression ratio to compress a medical image to be diagnosed at an optimal ratio; a processor for obtaining an optimal compression ratio of the medical image to be diagnosed by using the stored initial learning data and the equation for the optimal compression ratio; and for compressing the medical image to be diagnosed at the optimal compression ratio obtained by the computation unit.

  • Patent number: 7113186
    Abstract: A reference image is displayed by processing spatial distribution to image data recording. A screen for inputting a corresponding command is displayed when requested. A corresponding slab is a three-dimensional slab rendered according to an input of a slab control command on a displayed screen. The three-dimensional rendered slab is also displayed. When the slab control command is designated among the Sagittal image, the Coronal image, and the Axial image on the displayed screen, the image designated on the basis of the reference image is displayed. When the slab control command is designated as a request to Rotate on the displayed screen, it is checked whether a new rotation center is designated. When the new rotation center is designated, volume or interest (VOI) planes are rotated on the basis of the new rotation center and the image is generated and displayed.

  • Patent number: 7102634
    Abstract: An apparatus and method for displaying a three-dimensional virtual endoscopic image are provided. In the method, information on a virtual endoscopic image is input in the form of volume data expressed as a function of three-dimensional position. A two-dimensional reference image, a three-dimensional reference image, and a virtual endoscopic image are detected from the volume data. The detected images are displayed on one screen. Virtual cameras are respectively displayed on areas, in which the two and three-dimensional reference images are respectively displayed. Here, a camera display sphere and a camera display circle are defined on the basis of a current position of each virtual camera. When information regarding to one image, among the two and three-dimensional reference images and the virtual endoscopic image on one screen, is changed by a user's operation, information regarding to the other images is changed based on the information changed by the user's operation.

  • Publication number: 20040109032
    Abstract: Disclosed are a three-dimensional slab rendering system and method and a computer readable recording medium for storing the method. It is possible to provide detailed information on a volume of interest (VOI) by setting the VOI of a three-dimensional humanbody from a reference image, extracting and visualizing a three-dimensional image of only the VOI, and processing the extracted image. A reference image is displayed by processing spatial distribution to image data recording to the manipulation of a user. A screen for inputting a corresponding command is displayed when it is requested to display an image for inputting a slab control command. A corresponding slab is three-dimensional slab rendered according to an input of a slab control command on a displayed screen. The three-dimensional slab rendered slab is displayed.
