VIDEO ENCODING METHOD AND APPARATUS THEREFOR USING MODIFICATION VECTOR INDUCEMENT, VIDEO DECODING METHOD AND APPARATUS THEREFOR

摘要

A video decoding method according to an embodiment may include: determining whether a neighboring block adjacent to a current block has a direction vector indicating a specific location in an image; when the neighboring block does not have the direction vector, generating a disparity vector of a neighboring block indicating a specific location in an image having a different view from a view of an image of the neighboring block.

1. A video decoding method, which is performed by a video decoding apparatus, the video decoding method comprising:
obtaining a bitstream of an encoded image; determining a prediction mode of a current block by using prediction mode information of the current block that is included in the bitstream; determining a type of a reference vector, which indicates a reference block used for decoding the current block according to the prediction mode of the current block, as one of a motion vector type and a disparity vector type; when a neighboring block adjacent to the current block does not have the determined type of the reference vector, generating a reference vector of the neighboring block having the determined type; determining the reference vector of the current block indicating the reference block by using the generated reference vector of the neighboring block; obtaining information of the reference block by using the reference vector of the current block; and decoding the current block by using the information of the reference block.
