MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202527100374 A) filed by Huawei Technologies Co. , Ltd. on October 16, 2025, for Method And Apparatus For Image Encoding And Decoding.
Inventors include Solovyev, Timofey Mikhailovich; Karabutov, Alexander Alexandrovich; Alshina, Elena Alexandrovna; and Shi, Yibo.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: The present disclosure provides techniques for improving signaling efficiency in the context of rate control governing a desired ratio of bitrate load and quality in image compression. It is provided a method for encoding an image comprising obtaining the image, encoding the image into a bitstream based on a first coding parameter, wherein the first coding parameter is indicative of a first displacement between a first target rate control parameter and a first reference rate control parameter, and encoding the first coding parameter into the bitstream. Further, it is provided a method for decoding an image, comprising receiving a bitstream comprising coded data of the image, parsing the bitstream to obtain a first coding parameter, wherein the first coding parameter is indicative of a first displacement between a first target rate control parameter and a first reference rate control parameter, and reconstructing the image based on the first coding parameter.
