ALEXANDRIA, Va., Sept. 17 -- United States Patent no. 12,418,681, issued on Sept. 16, was assigned to QUALCOMM Inc. (San Diego).
"Context modeling for sign prediction for video coding" was invented by Vadim Seregin (San Diego), Louis Joseph Kerofsky (San Diego) and Marta Karczewicz (San Diego).
According to the abstract* released by the U.S. Patent & Trademark Office: "A video coder may code a sign prediction syntax element that indicates whether a sign prediction hypothesis is correct for a transform coefficient. The video coder may code the sign prediction syntax element using a context-based coding process. The video coder may determine a context for coding the sign prediction syntax element based on a position of the transform coeffic...
