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.
Claims20
A video processing method, comprising:
- 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.
A video processing apparatus, comprising:
- at least one memory for storing instructions;
- and
- at least one processor configured to execute the instructions to cause the apparatus to perform:
- 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.
A non-transitory computer readable storage medium storing a set of instructions that are executable by one or more processing devices to cause a video processing apparatus to perform a method comprising:
- 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.
