Title: Method and apparatus for encoding image, and method and apparatus for decoding image
Inventor: BAE KEUN LEE
IPC: H04N19/80
Filed: 2012-11-02
Abstract: Reference samples (e.g. a(0,0), to r(0,0)) are generated for a 4x4 prediction block by deriving a first sub-sample (e.g. a(0,0), b(0,0), c(0,0)) based on a horizontal interpolation filter and then deriving a second sub-sample (e.g. e(0,0) to r(0,0)) based on a vertical interpolation filter, where the vertical filter uses values calculated from the first sub-sample. The first sub-sample is derived using a first shifting value and an 8-tap horizontal interpolation filter (e.g. combining 8 integer samples including A(-1,0), A(0,0), A(1,0)). The second sub-sample is one of two quarter position samples (e.g. e(0,0), p(0,0)) and a half position sample (e.g. i(0,0)), and is vertically aligned below the first sub-sample (e.g. a(0,0)). The second sub-sample is derived based on a second shifting value and an 8-tap vertical interpolation filter (e.g. combining 8 first sub-samples including a(0,-1), a(0,0), a(0,1), a(0,2)). The first and second shifting values are based on a bit-depth of a luma component and a constant value respectively. Coefficients for the quarter and half position samples are different from one another. Prediction samples of a current block are obtained using the reference samples, and the current block is reconstructed using residual samples obtained from the video signal and the prediction samples.
