Abstract:
A method for video coding includes encoding or decoding a coding block in a current picture with an affine motion model based inter-picture prediction method in a video coding system, storing affine motion information of the coding block in a history-based motion vector prediction (HMVP) buffer that is configured for storing affine motion information candidates each including affine motion information of a processed affine-coded coding block, and constructing a motion candidate list for a current block that includes at least one candidate selected from the affine motion information candidates stored in the HMVP buffer or derived from one of the affine motion information candidates stored in the HMVP buffer.

Claim (Index 20):
A non-transitory computer-readable medium storing instructions that, when executed by a computer, cause the computer to perform:\n encoding or decoding a coding block in a current picture with an affine motion model based inter-picture prediction method, the coding block having affine motion information that includes one or more affine motion information parameters; determining a difference between (i) the one or more affine motion information parameters of the coding block and (ii) one or more affine motion information parameters of each entry of a history-based motion vector prediction (HMVP) buffer that is configured to store affine motion information candidates each including the one or more affine motion information parameters of a processed affine-coded coding block; in response to a determination that the determined difference between the one or more affine motion information parameters of the coding block and the one or more affine motion information parameters of each entry in the HMVP buffer is greater than or equal to a threshold, storing the one or more affine motion information parameters of the coding block in the HMVP buffer; and constructing a motion candidate list for a current block that includes at least one candidate selected from the affine motion information candidates stored in the HMVP buffer or derived from one of the affine motion information candidates stored in the HMVP buffer.
