Abstract: PURPOSE: A multiview video decoding method and a device thereof are provided to improve the quality of a depth image by applying an anisotropic median filter. CONSTITUTION: A decoder determines whether a current pixel area in a restored depth image is an edge area or not(S900). If the current pixel area is the edge area, the decoder classifies pixels in the current pixel area into groups based on a pixel value applied to an anisotropic median filter(S910). The decoder a filtering target pixel value based on a median value of the classified pixels(S920).

Abstract: PURPOSE: A method for encoding/decoding a depth image and an apparatus thereof are provided to enable a decoder to correct errors generated during a depth image coding/decoding process using characteristic information of a depth image. CONSTITUTION: A depth image decoder receives characteristic information of a depth image (S910). The depth image decoder decodes the received characteristic information of the depth image (S920). When the decoding of the received characteristic information is completed, the depth image decoder decodes the depth image using the decoded characteristic information (S930).

Abstract: PURPOSE: A depth map information encoding method and a device using the same are provided to encode depth map information based on encoding mode information used in encoding/decoding color image information. CONSTITUTION: An inter-screen prediction mode information used in a color image is provided (S200). It is determined whether an intra-screen prediction mode of a color image call block and an intra-screen prediction mode of a depth map image are the same (S210). If the two intra-screen prediction modes are the same, it is displayed that the two intra-screen prediction modes are the same (S220). If the two intra-screen prediction modes are not the same, the intra-screen prediction mode of the depth map image block is encoded (S230). [Reference numerals] (AA) Start; (BB) Finish; (S200) Color image is provided; (S210) Intra-screen prediction mode of color image is provided; (S220) Two intra-screen prediction mode of color image is provided; (S230) Depth map image block is encoded
