摘要： A video decoding method includes the steps of: generating a merge candidate list for a first block; selecting one among merge candidates included in the merge candidate list; and performing motion compensation for the first block based on motion information of the selected merge candidate. At this point, an inter-region merge candidate included in an inter-region motion information list may be added to the merge candidate list based on the number of spatial merge candidates and temporal merge candidates included in the merge candidate list.

摘要： A video decoding method according to the present disclosure includes the steps of: generating a merge candidate list for a current block; determining a merge candidate for the current block among merge candidates included in the merge candidate list; deriving an offset vector for the current block; and deriving a motion vector for the current block by adding the offset vector to a motion vector of the merge candidate.

摘要： A method for decoding an image, according to the present invention, comprises the steps of: determining whether a coding block is divided into a first prediction unit and a second prediction unit; determining a partition type of the coding block when determining that the coding block is divided; deriving first motion information about a first prediction unit and second motion information about a second prediction unit within the coding block; and acquiring a prediction sample within the coding block on the basis of the first motion information and the second motion information.

摘要： An image decoding method according to the present invention comprises the steps of: generating a merge candidate list in a current block; specifying one of a plurality of merge candidates included in the merge candidate list; deriving a first affine seed vector and a second affine seed vector of the current block on the basis of a first affine seed vector and a second affine seed vector of the specified merge candidate; deriving an affine vector for a subblock in the current block, using the first affine seed vector and the second affine seed vector of the current block; and performing motion compensation prediction for the subblock on the basis of the affine vector.

摘要： An image decoding method according to the present disclosure may include the steps of: determining whether a combined prediction mode is applied to a current block; when the combined prediction mode is applied to the current block, obtaining first and second prediction blocks with respect to the current block; and, on the basis of a calculation of a weighted sum of the first and second prediction blocks, obtaining a third prediction block with respect to the current block.

摘要： An image decoding method according to the present invention comprises the steps of: deriving a merge candidate of a current block from a neighboring block of the current block; adding the derived merge candidate to a merge candidate list; when the number of merge candidates previously added to the merge candidate list is less than a threshold value, adding at least one prediction area merge candidate included in a prediction area motion information table to the merge candidate list; deriving motion information about the current block on the basis of the merge candidate list; and performing motion compensation on the current block on the basis of the derived motion information.
