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 3):
The video decoding method of  claim 1 , wherein when the intra prediction mode of the current block is a horizontal mode, the filtered prediction value is generated by applying the second filter to uppermost pixels of the current block among prediction pixels of the current block adjacent to the boundary of the reference pixel value.
