Abstract:
Intra- or inter-prediction can be used for video encoding and decoding. For that purpose, an apparatus and methods obtain a filter (a set of coefficients) from a set of filters based on the subsample position (p) defined for the set of positions of predicted samples, where the set of filters is obtained by combining at least two pre-defined input filter sets.
