  • Publication number: 20220264148
    Abstract: Intra-prediction with modified clipping is presented herein for encoding and/or decoding video and/or still images. Input boundary samples for a current block are used to generate a reduced prediction matrix of prediction samples. Clipping is performed on each of the prediction samples in the reduced prediction matrix that are out of range to generate a clipped reduced prediction matrix. The clipped reduced prediction matrix is then used to generate the complete prediction block corresponding to the current block. The prediction block is then used to obtain a residual block. By clipping the prediction sample(s) in the reduced prediction matrix, the solution presented herein reduces latency and complexity.
