Abstract: A current block is coded by an affine mode and includes a first control point at a first corner of the current block. A current template associated with the first control point is determined. A plurality of candidate reference templates is determined in a reference picture for the current template.

The TM cost indicates a respective difference between each candidate reference template and the current template of the first control point. A first control point motion vector (CPMV) is determined based on the selected reference template, where the first CPMV indicates an offset between the selected reference template in the reference picture and the current template associated with the first control point. The current block is reconstructed based at least on the first CPMV.
