Abstract:
Provided is a method and apparatus for performing intra-prediction using an adaptive filter. The method for performing intra-prediction includes the steps of: determining whether or not to apply a first filter for a reference pixel value on the basis of information of a neighboring block of a current block; applying the first filter for the reference pixel value when it is determined to apply the first filter; performing intra-prediction on the current block on the basis of the reference pixel value; determining whether or not to apply a second filter for a prediction value according to each prediction mode of the current block, which is predicted by the intra-prediction performance on the basis of the information of the neighboring block; and applying the second filter for the prediction value according to each prediction mode of the current block when it is determined to apply the second filter.

Claim (Index 1):
A video decoding method, comprising:\n determining whether to apply a first filter to a reference pixel value of a current block based on at least one of an intra prediction mode of the current block and a size of the current block; deriving a prediction value of the current block using the reference pixel value; and determining whether to apply a second filter to the prediction value of the current block based on at least one of an intra prediction mode of the current block and a size of the current block, for thereby producing a filtered prediction value, wherein the first filter is applied based on comparison of a calculation value calculated using reference pixel values and a specific threshold.
