Abstract
An encoder or decoder projects, in an angular direction, a location of a sample in a block to a point on a reference line between a plurality of reference samples. The encoder or decoder selects a filter coefficient table, from among a plurality of filter coefficient tables, based on the angular direction and a size of the block. The encoder or decoder selects first filter coefficients from the filter coefficient table based on a fractional part of a displacement of the point on the reference line relative to the location of the sample. The encoder or decoder applies, to the plurality of reference samples, the first filter coefficients to determine a first filtered value. The encoder or decoder determines a prediction of the sample based on the first filtered value.
