ALEXANDRIA, Va., Aug. 20 -- United States Patent no. 12,395,655, issued on Aug. 19, was assigned to QUALCOMM Inc. (San Diego).
"Chroma from luma prediction for video coding" was invented by Dhruv Aggarwal (San Jose, Calif.), Anand Singh (Carlsbad, Calif.) and Akarsh Ningoji Rao Kolekar (San Diego).
According to the abstract* released by the U.S. Patent & Trademark Office: "A video coder may be configured to code a chroma block of video data as a function of reconstructed luma samples. The video coder may store, during the prediction process for a luma block, a sum of the reconstructed luma sample values for each sub-block of the luma block in a first buffer, and store, during the prediction process for the luma block, an average of the re...
