METHODS AND APPARATUSES FOR MOTION COMPENSATION

Abstract:

The present disclosure provides methods for motion compensation. The method can include: determining intermediate interpolation coefficients of an interpolation filter based on a position of an integer sample and a fractional position of a fractional sample; determining integer interpolation coefficients of the interpolation filter, comprising rounding each of the intermediate interpolation coefficients to an integer; and applying the interpolation filter on a picture to perform motion compensation prediction.
