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). [Reference numerals] (S910) Receive characteristic information of a depth image; (S920) Decode the received characteristic information of the depth image; (S930) Decode the depth image using the decoded characteristic information

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). [Reference numerals] (AA) Start; (BB) End; (S900) Determine an edge area; (S910) Classify pixels within a current pixel area; (S920) Determine a filtering target pixel value

Abstract: PURPOSE: A video encoding and decoding apparatus and a method using context information based adaptive post filter are provided to improve the efficiency of video encoding. CONSTITUTION: A reconstitution video generator(120) creates the reconstructed image using the differential signal and the restored prediction frame. The reconstitution video generator applies the deblocking filter. A post filter unit(130) decides whether to apply the fixed post filter based on the contextual information of the reconstructed image to the reconstructed image. The post filter unit decides whether to apply the post filter adaptively based on the contextual information of the reconstructed image to the reconstructed image. The post filter unit applies the fixed post filter or the post filter which was adaptively generated to the reconstructed image.
