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 5):
The video encoding method of  claim 4 , wherein when the intra prediction mode of the current block is a DC mode, as the second filter, a 3-tap filter is applied to an upper-leftmost pixel of the current block among prediction pixels of the current block and a 2-tap filter is applied to remaining uppermost and leftmost pixels except the upper-leftmost pixel among the prediction pixels of the current block, and\n wherein the upper-leftmost pixel corresponds to a first filter coefficient and the remaining uppermost and leftmost pixels correspond to a second filter coefficient, wherein the second filter coefficient is 1.5 times larger than the first filter coefficient.
