Abstract

An apparatus includes at least one processor for decoding a block of a picture using intra-prediction that is configured to: decode, from a data stream, a mode index, the mode index indicating a matrix-based intra-prediction mode out of a plurality of matrix-based intra-prediction modes based on a size of the block, derive an input vector based on downsampling reference samples neighboring the block, determine a matrix based on the size of the block and the mode index, compute a respective output for each component of a matrix-vector product between the input vector and the determined matrix, the respective output computed by performing, a right shift by a number of bits which is independent of the matrix-based intra-prediction mode indicated by the mode index, and for each component of the matrix-vector product, use the respective output to predict a respective sample of the block.
