Method and device image interpolation using an interpolation filter smoothing

摘要

An apparatus for motion compensation, the apparatus comprising: a selector filter is configured to select a filter 8-tap interpolation samples brightness, and an interpolator that is configured to determine, in a reference image brightness, a reference block brightness for predicting a current block using a motion vector of the current block brightness, and brightness to generate a sample of a location 1/2 pixel included in the reference block by applying the filter brightness 8 take samples of brightness of a location integer pixel of the reference image brightness, wherein the filtering selector selects a filter for interpolation of color samples, the interpolator determines a reference image color a block color reference for predicting the current block using a motion vector of the current block color, and generating a color sample locatio ion 1/2 pixel included in the reference block by applying the color filter color samples integer pixel location of the reference image color filter comprises eight 8-tap filter coefficients to generate the sample brightness 1/2 pixel location, which are {-1, 4, -11, 40, 40, -11, 4, -1}.
