US Patent Issued to QUALCOMM on May 13 for "Transform and last significant coefficient position signaling for low-frequency non-separable transform in video coding" (California Inventors)

ALEXANDRIA, Va., June 12 -- United States Patent no. 12,301,876, issued on May 13, was assigned to QUALCOMM Inc. (San Diego).

"Transform and last significant coefficient position signaling for low-frequency non-separable transform in video coding" was invented by Alican Nalci (La Jolla, Calif.), Hilmi Enes Egilmez (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 video decoder determines, based on a block size of a current block and a low-frequency non-separable transform (LFNST) syntax element, a zero-out pattern of normatively defined zero-coefficients. The LFNST syntax element is signaled at a tra...
