=== What are the specific parameters related to pixel group unit motion compensation mentioned in the abstract? ===

The abstract mentions obtaining a parameter related to pixel group unit motion compensation, but it does not specify the exact parameters or how they are calculated.

=== How does the method handle different reference pictures in the video decoding process? ===

The abstract describes obtaining motion vectors from different reference pictures for the current block, but it does not detail how the method selects or prioritizes these reference pictures.


==Original Abstract Submitted==

Provided is a video decoding method including: obtaining a first motion vector indicating a first reference block of a current block in a first reference picture and a second motion vector indicating a second reference block of the current block in a second reference picture; obtaining a parameter related to pixel group unit motion compensation of the current block, based on at least one of information of the parameter related to the pixel group unit motion compensation and a parameter related to an image including the current picture; generating a prediction block by performing, with respect to the current block, block unit motion compensation based on the first motion vector and the second motion vector and performing the pixel group unit motion compensation based on the parameter related to the pixel group unit motion compensation; and reconstructing the current block. Here, a pixel group may include at least one pixel.
