Abstract:
Disclosed herein are a method and apparatus for filtering a reference pixel. A method of smoothing a reference pixel may include determining whether or not to perform smoothing on a reference pixel based on the size of a transform block and information about an intra-prediction mode for the transform block and determining a smoothing method by comparing the size of the transform block with the size of a maximum transform block. Accordingly, image coding efficiency can be increased, and picture quality can be improved.

Claim (Index 9):
The image decoder of  claim 7 ,\n wherein the bi-linear smoothing filter is a filter for calculating a filtered reference pixel, pF[x][y] (x=\u22121, y=\u22121 . . . nT*2\u22121, x=\u22121 . . . nT*2\u22121, y=\u22121), according to:\n pF[\u2212 1][ nT* 2\u22121]= p[\u2212 1][ nT* 2\u22121] \n pF[nT* 2\u22121][\u22121]= p[nT* 2\u22121][\u22121] \n pF[\u2212 1][ y ]=( nT* 2\u22121\u2212 y )* p[\u2212 1][\u22121]+( y+ 1)* p[\u2212 1][ nT* 2\u22121]+ nT )>>(1+log 1 ( nT )) for  y= 0 . . .  nT* 2\u22122 \n pF[\u2212 1][\u22121 ]=p[\u2212 1][\u22121] \n pF[x][\u2212 1]=(( nT* 2\u22121\u2212 x )* p[\u2212 1][\u22121]+( x+ 1)* p[nT* 2\u22121][\u22121]+ nT )>>(1+log 2 ( nT )) for  x= 0 . . .  nT* 2\u22122 \n wherein the current block is a current transform block and the size of the current block is a size of a current transform block, and wherein the size of the transform block is nT, and a reference pixel of the transform block is\n p[x][y ]( x=\u2212 1, y=\u2212 1 . . .  nT* 2\u22121, x=\u2212 1 . . .  nT* 2\u22121, y=\u2212 1).
