  • 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.
