  • Publication number: 20080317361
    Abstract: A method and apparatus for encoding/decoding an image are provided. The method includes partitioning an image into a plurality of areas, allocating the partitioned plurality of areas to views of multi-view image sequences, and encoding the allocated plurality of areas. By doing so, the method can efficiently encode a large-screen image or a high-pixel image, without using a separate codec.

  • Publication number: 20080240590
    Abstract: Methods and apparatuses for encoding and decoding a multi-view image are provided. The method of encoding the multi-view image can use a difference in views between pictures of the multi-view image, add an image area obtained from a picture at one view at a first time to a picture at another view at a second time, thereby generating a reference picture, and perform prediction encoding using the generated reference picture, thereby increasing prediction encoding efficiency.

  • Publication number: 20080170629
    Abstract: Provided are a method and an apparatus for filtering video data. The method includes determining whether a difference value of illumination change (DVIC) of a current image processing unit containing a current block is different from a DVIC of an image processing unit that is adjacent to the current image processing unit and based on the determining, adjusting a filtering strength of a deblocking filter and performing deblocking filtering on a boundary of the current block using the filter with the adjusted filtering strength.

  • Publication number: 20080170618
    Abstract: Provided are a method and apparatus for encoding and decoding multi-view images. The multi-view image encoding method includes predicting a motion vector of a current block, based on information indicating a disparity between a current picture to which the current block belongs and a different picture having a view-point which is different from a view-point of the current picture, and encoding the current block in a skip mode based on the predicted motion vector of the current block.

  • Publication number: 20080159638
    Abstract: A method and apparatus for encoding and decoding multi-view images. The multi-view image encoding method selects a block corresponding to a current block from another picture having a view-point which is different from a view-point of a current picture to which the current block belongs, on the basis of a global disparity vector representing a global disparity between the current picture and the other picture; and encodes the current block on the basis of block information of a block from among the selected block and blocks adjacent to the selected block. Accordingly, multi-view images can be encoded in consideration of the individual differences between the appearances of objects as well as global disparities between view-points.

  • Publication number: 20080089596
    Abstract: Provided is a method and apparatus for encoding and decoding a multi-view image. By predicting a current picture based on at least one of an intra (I) picture of a previous image processing block and an I picture of a current image processing block, which is generated for a different view than a view at which the I picture of the previous image processing block is generated, and encoding the current picture based on the prediction, it is possible to prevent display quality degradation that may occur in images at views other than a base view.
