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 3):
The intra-prediction method of  claim 1 , wherein the smoothing filter having the filtering coefficients of [1,2,1] is a filter for calculating a filtered reference pixel,\n pF[x][y ]( x=\u2212 1, y=\u2212 1 . . .  nT* 2-1, x=\u2212 1 . . .  nT* 2-1, y=\u2212 1), according to the equations:\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 ]=( p[\u2212 1][ y+ 1]+2* p[\u2212 1][ y]+p[\u2212 1][ y\u2212 1]+2)>>2 for  y=nT* 2\u22122 . . . 0 \n pF[\u2212 1][\u22121]=( p[\u2212 1][0]+ 2 * p[\u2212 1][\u22121]+ p[ 0][\u22121]+2)>>2 \n pF[x][\u2212 1]=( p[x\u2212 1][\u22121]+2* p[x][\u2212 1]+ p[x+ 1][\u22121]+2)>>2 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 current transform block is nT, a reference pixel of the current transform block is\n p[x][y ]( x=\u2212 1, y=\u2212 1 . . .  nT* 2\u22121, x=\u2212 1 . . .  nT* 2\u22121, y= 1).
