US Patent Issued to QUALCOMM on Sept. 23 for "Derivation of affine merge candidates with linear regression for video coding" (California Inventors)

ALEXANDRIA, Va., Sept. 23 -- United States Patent no. 12,425,643, issued on Sept. 23, was assigned to QUALCOMM Inc. (San Diego).

"Derivation of affine merge candidates with linear regression for video coding" was invented by Yan Zhang (San Diego), Han Huang (San Diego), Vadim Seregin (San Diego), Muhammed Zeyd Coban (Carlsbad, Calif.) and Marta Karczewicz (San Diego).

According to the abstract* released by the U.S. Patent & Trademark Office: "A method for coding a block of video data using affine mode includes determining a refined affine model for the current block of video data from a linear regression process using a base motion vector field and a guidance motion vector field as inputs to the linear regression process. The method furth...
