FRACTIONAL PIXEL INTERPOLATION FILTER FOR VIDEO COMPRESSION

摘要

In one embodiment, a method for encoding or decoding video content is provided. The method includes receiving a plurality of full-pel pixel values. A set of coefficients is determined for an interpolation filter to interpolate a sub-pel pixel value for a motion compensation operation. Different coefficients are assigned to weight the plurality of full-pel pixel values in different operations in the interpolation filter. The sub-pel pixel values from the different operations are determined. Then, the method outputs the interpolated sub-pel pixel value for use in the motion compensation operation.
