Abstract
To generate an improved image signal when estimating motion, a motion vector is first determined with pel accuracy, and a two-step interpolation filtering is subsequently carried out with sub-pel accuracy. The interpolation coefficients are selected with a view to reducing aliasing. More neighboring pixels are used for the interpolation than in usual interpolation methods. One is able to improve the quality of the prediction signal for video images and, consequently, enhance coding efficiency.
