Abstract:
1. A method of motion compensation, the method comprising: determining, in a luma reference picture, a luma reference block for prediction of a current block, by using a luma motion vector of the current block; generating a luma sample of a 2/4-pixel location included in the luma reference block by applying an 8-tap filter to luma samples of an integer pixel location of the luma reference picture; determining, in a chroma reference picture, a chroma reference block for prediction of a current block, by using a chroma motion vector of the current block; and generating at least one chroma sample of at least one of ⅛, 2/8, and ⅜-pixel locations included in the chroma reference block by applying a 4-tap filter to chroma samples of an integer pixel location of the chroma reference picture; wherein the 8-tap filter includes eight filter coefficients, and the 4-tap filter includes four filter coefficients.
