Abstract
The various implementations described herein include methods and systems for encoding and decoding video. In one aspect, a method of video decoding includes receiving video data that includes a first block from a video bitstream, where the first block is predicted in an angular prediction mode. The method also includes identifying a set of reference samples for a portion of the first block using a prediction angle for the angular prediction mode and deriving a first angular prediction value for the portion using at least a first subset of the set of reference samples. The method further includes deriving a second angular prediction value for the portion using a weighted sum of at least a second subset of the set of reference samples and the first angular prediction value and decoding the portion using the second angular prediction value.
