Intellectual Property India Publishes Patent Application for 'Image Encoding/Decoding Method, Method For Transmitting Bitstream, And Recording Medium On Which Bitstream Is Stored' Filed by Lg Electronics Inc.

MUMBAI, India, Aug. 1 -- Intellectual Property India has published a patent application (202517063125 A) filed by Lg Electronics Inc., Seoul, Republic of Korea, on July 2, for 'image encoding/decoding method, method for transmitting bitstream, and recording medium on which bitstream is stored.'

Inventor(s) include Tan, Hendry.

The application for the patent was published on Aug. 1, under issue no. 31/2025.

According to the abstract released by the Intellectual Property India: "An image encoding/decoding method, a bitstream transmission method, and a computer-readable recording medium on which a bitstream is stored are provided. The image decoding method according to the present disclosure comprises the steps of: acquiring a neural-network post-filter (NNPF) supplemental enhancement information (SEI) message; determining, on the basis of at least one neural-network post-filter characteristics (NNPFC) SEI message included in the NNPF SEI message, at least one neural network that can be used as a post-processing filter, on the basis that the NNPF SEI message is applied to the current picture; and determining, on the basis of at least one neural-network post-filter activation (NNPFA) SEI message included in the NNPF SEI message, whether a target neural network post-processing filter applicable to the current picture is activated, wherein the target neural network post-processing filter is determined as a neural network post-processing filter of the last NNPFC SEI message, from among the NNPFC SEI messages, of a decoding order."

The patent application was internationally filed on Jan. 18, 2024, under International application No.PCT/KR2024/000896.
