Abstract
The present disclosure provides intra prediction methods for video or image coding. An exemplary method includes: performing an intra predicting process for a target block, wherein performing the intra predicting process comprises: determining an intra prediction mode for the target block; in response to the intra prediction mode is an angular mode, determining a filtered value by applying an N-tap interpolation filter to a plurality of reference samples surrounding the target block based on the angular mode, wherein N is an integer greater than 4; and determining a predicted value of a sample of the target block based on the filtered value.
