Claim 3:
4. The method of claim 1, wherein the first component is a horizontal component, with the first array of first-component gradients being a first horizontal gradient array, the second array of first-component gradients being a second horizontal gradient array, the first-component intermediate parameter array being a horizontal intermediate parameter array obtained by performing a right bit shift on a sum of the first horizontal gradient array and the second horizontal gradient array, and the first-component motion refinement being a horizontal motion refinement, the method further comprising:
obtaining a first vertical gradient array based on the first prediction signal array from the first reference picture;
obtaining a second vertical gradient array based on the second prediction signal array from the second reference picture;
obtaining a vertical intermediate parameter array including performing a right bit shift on a sum of the first vertical gradient array and the second vertical gradient array; and
obtaining a vertical motion refinement based at least in part on the horizontal intermediate parameter array and the vertical intermediate parameter array;
wherein the prediction of the current block is generated using the horizontal motion refinement and the vertical motion refinement.
