MUMBAI, India, June 30 -- Intellectual Property India has published a patent application (202617047633 A) filed by Kaon Group Co. , Ltd.; and University-Industry Cooperation Group Of Kyung Hee on April 14, 2026, for Video Encoding/Decoding Method And Device Based On Improved Local Illumination Compensation Template Determination.
Inventors include Ryu, Chang Woo; and Choi, Ki Ho.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: The present invention relates to a video compression technology and, more specifically, to the improvement of a local illuminance compensation (LIC) technology included in a prediction coding technology contributing to the improvement of compression performance in a video encoder and decoder. A method for decoding an encoded video bitstream, according to one embodiment of the present invention, comprises the steps of: extracting, from a bitstream, information related to local illumination compensation (LIC) for the current block, and acquiring LIC information from the extracted information; determining at least one linear model on the basis of the LIC information; generating a prediction sample for the current block by means of an LIC method using the linear model; and using the prediction sample so as to restore the current block, wherein the linear model is defined as either a linear function or a quadratic function.
