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 4):
The video decoding method of  claim 3 , wherein when the intra prediction mode of the current block is the horizontal mode, the second filter is applied by using a left reference pixel value, upper reference pixel values and an upper-left corner reference pixel value, the left reference pixel value corresponding to a left-side of an upper-leftmost pixel of the current block, the upper reference pixel values corresponding to upper-sides of the uppermost pixels of the current block.
