Abstract:
PURPOSE: A method for generating a virtual view image and an apparatus thereof are provided to compensate a non-processed region more accurately by estimating an edge within the non-processed region of the virtual view image through the edge information of the virtual view image. CONSTITUTION: The base view images for plural reference view cameras are synthesized, and a virtual view image is created for the virtual view camera through the synthesis(301). The edge information of the virtual view image is extracted through an edge operator(303). The edge operator is a Sobel and Cannly operator. Based on the edge information, the non-processed region is compensated(305). In the compensation of the non-processed region, the edge estimation and the pixel value compensation are performed.

PURPOSE: A method for providing a region based broadcasting service using digital multimedia broadcasting, and an apparatus and a method for receiving a region based broadcasting service according to the method are provided to supply a region or location based DMB service, thereby providing profitable information about a specific region or providing various information related to a location to a viewer who moves. CONSTITUTION: A location information obtaining unit(601) obtains location information of a receiving device. A broad area data receiving unit(602) extracts broad area service data and local area common control information from a broad broadcasting signal. A local area data receiving unit(603) receives a local area broadcasting signal corresponding to a current location using the obtained location information and the extracted local area common control information and extracts local area service data. An LBS(Location Base Service) processor(604) receives corresponding extraction information from the broad or local area data receivers and provides it to an LBS.

Abstract:
A multi-view matching method and apparatus for using object or background separation are provided to improve depth discontinuous boundary detection performance by using depth information with color information in object or background separation. The multi-view image received from a multi-view camera and the depth information of a reference viewpoint image received from a depth camera are stored(S101). The object or background area separation of the reference viewpoint image is performed by using the reference viewpoint image and the depth information(S102). The final depth information of the reference viewpoint image is determined(S103). The final depth information of a viewpoint image except a reference viewpoint among multi-view points is determined by using the final depth information of the reference viewpoint image (S104). The final depth information of each multi-view image is recorded as a digital image(S105).

Abstract:
An object description method for the 3D(Dimensional) stereoscopic video service based on DMB(Digital Multimedia Broadcasting), a method for receiving the 3D stereoscopic video service and a method for converting the image format according to the object description method are provided to minimize the bandwidth needed to the 3D stereoscopic video service without deterioration of the image quality. A process for setting a broadcasting type within an object descriptor(20) relating to the reference image whether a broadcasting service is 2D broadcasting or 3D broadcasting is performed. The reference image(21) and depth information(22) relating to the 3D stereoscopic image as an object of the broadcasting service are described by one object descriptor. In the process for setting the broadcasting type, the broadcasting type is defined by the contents type descriptor. In the object description process, the ESD(Elementary Stream Descriptor)s relating to the reference image and the depth information are constructed by the same OD(Object Descriptor) as the relation between master and servant.
