Abstract
The present disclosure provides methods and apparatuses for applying intra prediction refinement to intra predicted samples. An exemplary method includes: determining a filter based on neighboring samples of intra predicted samples of a picture; generating an offset value based on the neighboring samples; refining the intra predicted samples by adding the offset value; and applying the filter to the intra predicted samples.
