The application for the patent was published on October 02, 2026, under issue no. 40/2026.
Abstract: A method comprising: partitioning a block of a video into sub blocks; selecting an encoding mode using matrix-based intra prediction for the partitioned block, for each of the sub block, predicting samples of the sub block by: averaging samples of a line of reconstructed reference samples adjacent on top of the block and a column of reconstructed reference samples adjacent on the left of the block to determine a one-dimensional vector; determining a low-resolution version of a predicted sub block by multiplying the vector with a matrix; determining a full size resolution of the predicted sub block by performing a linear interpolation to expand the low-resolution version of the predicted sub block matrix to the size of the block; and encoding the block and signaling information, wherein the block is coded in intra-sub partition mode and the signaling information comprises at least an information representative of the use of matrixbased intra prediction for the block.
