MUMBAI, India, June 30 -- Intellectual Property India has published a patent application (202617047635 A) filed by Kaon Group Co. , Ltd.; and University-Industry Cooperation Group Of Kyung Hee on April 14, 2026, for Method And Apparatus For Encoding/Decoding Video On Basis Of Improved Template Determination For Local Illuminance Compensation.
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 video compression technology and, more specifically, to the improvement of local illuminance compensation (LIC) technology, which is included in prediction coding technology that contributes to the enhancement of compression performance in video encoders and decoders. A method for decoding an encoded video bitstream, according to an embodiment of the present invention, comprises the steps of: obtaining at least one prediction vector for a current block, which is currently being decoded from the bitstream; determining at least one reference block on the basis of the prediction vector; defining at least one of a first template which considers the current block to be a base block, and a second template which considers the reference block to be the base block; determining, for at least one of the templates, a template configuration mode that includes information on a method for using the template; on the basis of the at least one template configuration mode, obtaining LIC information by referring to information on at least one pixel derived from at least one of the templates; generating a prediction sample for the current block by correcting the reference block by means of an LIC method; and reconstructing the current block by using the prediction sample.
