MUMBAI, India, Nov. 14 -- Intellectual Property India has published a patent application (202517096021 A) filed by Interdigital Ce Patent Holdings, Sas, Paris, on Oct. 6, for 'weighted planar and dc modes for intra prediction.'
Inventor(s) include Rath, Gagan Bihari; Chen, Ya; Le Leannec, Fabrice; and Robert, Antoine.
The application for the patent was published on Nov. 14, under issue no. 46/2025.
According to the abstract released by the Intellectual Property India: "In one implementation, we propose to improve the PLANAR and DC prediction modes by introducing weights, for example, proportional to the sides of the block. The planar mode prediction is obtained by a weighted combination of the horizontal and vertical interpolations. Similarly, the DC value in the DC prediction mode is obtained as a weighted combination of the DC values computed from the top and the left reference arrays of a target block. When the target block is flat because of a high width to height ratio, or tall because of a high height to width ratio, the proposed methods are expected to produce better predictions than the equal weighted versions."
The patent application was internationally filed on Mar. 25, 2024, under International application No.PCT/EP2024/057958.
