  • Publication number: 20220311996
    Abstract: Disclosed herein are a method and apparatus for image encoding and decoding using prediction based on a block shape. Whether a prediction mode is available for a target block is determined. The determination is performed based on the shape of the target block. When the prediction mode is determined to be unavailable for the target block, signaling related to the prediction mode may be omitted, and determination of an additional prediction mode is performed. When the prediction mode is determined to be available for the target block, information indicating whether the prediction mode is to be used for the target block is signaled.

  • Publication number: 20220295059
    Abstract: Disclosed herein are a method, an apparatus, and a storage medium for image encoding/decoding using partitioning. Various prediction methods and prediction modes may be used for prediction of a block. When a block is partitioned, information related to partitioning, such as information indicating whether partitioning is to be performed and information specifying the type of partitioning, is signaled. Also, when partitioning is applied to the block, an available prediction method and an available prediction method in prediction for the block may be restricted in prediction for the block. For optimization of signaling, multiple pieces of information related to prediction may be signaled, wherein the pieces of information may have dependency relationships, and in some cases, additional information may be derived as specific values depending on the value of one piece of information, and signaling of the additional information may be skipped.

  • Publication number: 20220166973
    Abstract: An image encoding/decoding method and apparatus is provided. The method of decoding an image includes decoding at least one of prediction mode information of a neighbor block of a current block and length information of the current block, deriving an intra prediction mode of the current block into a predetermined mode using the decoded information, and reconstructing the current block based on the intra prediction mode of the current block.

  • Patent number: 10701396
    Abstract: The present invention relates to a video encoding/decoding method and apparatus, and more particularly, to a method and apparatus for generating a reference image for a multiview video. The video encoding method includes, in the presence of a second image having a different view from a first image having a first view, transforming the second image to have the first view, generating a reference image by adding the second image to a side of the first image, and storing the reference image in a reference picture list.
