Abstract
An apparatus comprising a processor configured to determine whether to apply an intra smoothing filter for a prediction unit (PU) based on a lookup table (LUT), wherein the LUT comprises data indicating the intra smoothing filter should not be applied for any PU with a block size of 8×8 pixels and associated with directional prediction mode. The disclosure also includes a method comprising generating reference samples, determining a size of a PU block, and selecting the reference samples based on PU block size, wherein filtered reference samples are not selected for PU blocks with a size of 8×8 pixels and associated with directional prediction mode.
