Intellectual Property India Publishes Patent Application for 'Factional Sample Interpolation For Reference Picture Resampling' Filed by Fraunhofer-Gesellschaft Zur Forderung Der Angewandten Forschung E. V.

MUMBAI, India, Aug. 29 -- Intellectual Property India has published a patent application (202518076345 A) filed by Fraunhofer-Gesellschaft Zur Forderung Der Angewandten Forschung E. V., Munchen, Germany, on Aug. 11, for 'factional sample interpolation for reference picture resampling.'

Inventor(s) include Bross, Benjamin; Sanchez De La Fuente, Yago; Skupin, Robert; Winken, Martin; Schwarz, Heiko; Marpe, Detlev; Schierl, Thomas; and Wiegand, Thomas.

The application for the patent was published on Aug. 29, under issue no. 35/2025.

According to the abstract released by the Intellectual Property India: "Concepts are described, including encoding of a video into data stream and decoding of a data stream having a video encoded thereinto, using motion compensation prediction between pictures of equal resolution and pictures of different resolution, based on motion vectors at a half-sample resolution and on motion vectors at a different resolution using interpolation filters to obtain sub-sample values within a reference sample array. The interpolation filter is selected from two interpolation filter versions different in a higher edge preserving property, and the selection is depending on whether a current picture is equal in picture resolution to the reference sample array in horizontal and/or vertical dimension, and/or a constraint information in the data stream."

The patent application was internationally filed on Dec. 21, 2020, under International application No.PCT/EP2020/087493.
