Motion vector prediction for affine motion models in video coding
A video decoder selects a source affine block. The source affine block is an affine-coded
block that spatially neighbors a current block. Additionally, the video decoder extrapolates
motion vectors of control points of the source affine block to determine motion vector
predictors for control points of the current block. The video decoder inserts, into an affine
motion vector predictor (MVP) set candidate list, an affine MVP set that includes the motion
vector predictors for the control points of the current block. The video decoder also …
