Abstract

A method and apparatus for video coding using regression MV derivation. According to the method, CPMVs for the current block, affine parameter sets or regression models are derived based on a non-adjacent affine-coded block. The CPMVs, affine parameter sets or regression models are blended with neighbouring MVs of subblocks within a neighbouring region associated with at least one of the CPMVs, affine parameter sets or regression models to generate at least one blended MV. A CPMV set comprising the blended MV is inserted into a merge candidate list. According to another method, a subset of subblocks of a non-adjacent affine-coded block is determined. A set of CPMVs or SBMVs are derived based on the subset of subblocks of the non-adjacent affine-coded block. The derived MVs are derived for the current block based on a regression process with input MVs including the set of CPMVs or SBMVs associated with the subset.
