Abstract:
An intra prediction method includes the steps of: acquiring intra prediction mode information from a bitstream; deriving neighboring samples of a current block; determining an intra prediction mode for the current block on the basis of the intra prediction mode information; deriving a prediction sample of the current block on the basis of the intra prediction mode and the neighboring samples; determining filtering reference samples for the prediction sample on the basis of the intra prediction mode; and deriving a filtered prediction sample by applying filtering to the prediction sample on the basis of the filtering reference samples. According to the present invention, a prediction sample can be adaptively filtered according to the intra prediction mode, and intra prediction performance can be improved.

Claim (Index 9):
The intra-prediction method according to  claim 6 , further comprising determining whether strong filtering or weak filtering is applied to the prediction sample,\n wherein the filter coefficients having different values depending on whether strong filtering or weak filtering is applied to the prediction sample are derived.
