US Patent Issued to QUALCOMM on Feb. 24 for "Regression-based decoder side affine motion derivation for video coding" (California Inventors)

ALEXANDRIA, Va., Feb. 24 -- United States Patent no. 12,563,198, issued on Feb. 24, was assigned to QUALCOMM Inc. (San Diego).

"Regression-based decoder side affine motion derivation for video coding" was invented by Han Huang (San Diego), Vadim Seregin (San Diego) and Marta Karczewicz (San Diego).

According to the abstract* released by the U.S. Patent & Trademark Office: "A video coder may be configured to partition a coding block into subblocks, and generate initial subblock motion vectors for a plurality of the subblocks. The video coder may further refine the initial subblock motion vectors for the plurality of the subblocks using decoder side motion vector refinement to produce refined subblock motion vectors for the plurality of the...
