Claim 14:
15. An apparatus for video coding, including:
at least one processor; and
a memory coupled to the at least one processor and storing executable instructions, which, when executed by the at least one processor, instruct the at least one processor to perform operations comprising:
intra-predicting a block; and
performing subpixel interpolation filtering to reference samples of the block using a subpixel interpolation filter;
wherein the subpixel interpolation filter is a combination of a plurality of filters, and filter coefficients of at least one of the plurality of filters is determined in accordance with a fractional sample position, wherein the subpixel interpolation filter is a sharpening filter that is a parallel combination of one phase-dependent linear filter and strength-varying high-pass filter.
