MUMBAI, India, Oct. 11 -- Intellectual Property India has published a patent application (202517089687 A) filed by Guangdong Oppo Mobile Telecommunications Corp. Ltd., Guangdong, China, on Sept. 19, for 'intra prediction method and apparatus based on interpolation filtering, video encoding method and apparatus, video decoding method and apparatus, and system.'
Inventor(s) include Xu, Luhang.
The application for the patent was published on Oct. 10, under issue no. 41/2025.
According to the abstract released by the Intellectual Property India: "An intra frame prediction method and apparatus based on interpolation filtering, a video encoding method and apparatus, a video decoding method and apparatus, and a system. The intra prediction method based on interpolation filtering comprises: during the intra prediction process of video encoding and decoding, determining, according to a filtering window of the current block and reconstruction values of pixel points in a reconstruction region adjacent to the current block, a filtering coefficient which is used when interpolation filtering is performed on the current block; and performing point-by-point prediction on the pixel points in the current block according to the filtering window and the filtering coefficient, so as to obtain a predicted block of the current block. In the embodiments of the present disclosure, a predicted block of the current block is obtained using the current block and the spatial redundancy of a reconstruction region adjacent thereto, such that the encoding performance can be improved."
The patent application was internationally filed on Feb. 24, 2023, under International application No.PCT/CN2023/078238.
