The filtering process to be applied to intra predicted sample values is selected and adapted based on the characteristics of the sample prediction process. According to some embodiments an angularity information and pixel values for filtering by a filter are received. The angularity information is used to adapt the filter. The adapting may comprise selecting a filter algorithm and/or filter coefficients. The selected pixels are then filtered by the adapted filter.
