Patent number: 12244864Abstract: A method for decoding a predetermined block of a picture using intra-prediction by reading, for each of predetermined intra-prediction blocks, from a data stream, a mode index identifying a matrix-based intra-prediction mode is disclosed. Samples of each predetermined intra-prediction block are predicted by computing a matrix-vector product between an input vector derived from reference samples and a prediction matrix associated with the identified matrix-based intra-prediction mode (k)—and associating components of an output vector obtained by the matrix-vector product onto sample positions of the predetermined block. Further predetermined intra-predicted blocks of the picture are predicted to obtain a prediction signal. A transformation flag is decoded from the data stream using context adaptive binary arithmetic coding, and a prediction residual is decoded and re-transformed using a reverse transformation based on the transformation flag to obtain a prediction residual signal.Type: GrantFiled: May 12, 2024Date of Patent: March 4, 2025Assignee: Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V.Inventors: Jonathan Pfaff, Björn Stallenberger, Michael Schafer, Philipp Merkle, Tobias Hinz, Philipp Helle, Heiko Schwarz, Detlev Marpe, Thomas Wiegand, Benjamin Bross, Martin Winken, Mischa Siekmann
