ALEXANDRIA, Va., Oct. 21 -- United States Patent no. 12,445,640, issued on Oct. 14, was assigned to QUALCOMM Inc. (San Diego).
"Methods of subblock skipping for affine motion search for video coding" was invented by Han Huang (San Diego), Yan Zhang (San Diego), Zhi Zhang (Munich), Vadim Seregin (San Diego) and Marta Karczewicz (San Diego).
According to the abstract* released by the U.S. Patent & Trademark Office: "Encoding and decoding video data using an affine decoder side motion vector derivation (DMVR) mode includes receiving a block of video data to be decoded using the affine DMVR mode, and dividing the block into a plurality of subblocks. A video encoder and video decoder may determine a final offset for the affine DMVR mode using ...
