Filtering Predictive Signals in Affine Linear Weighted Intra Prediction

摘要

A device for decoding video data determines that a current block of video data is encoded in an affine linear weighted intra prediction (ALWIP) mode, in a set of left edge neighboring samples of the current block and a set of upper edge neighboring samples of the current block. based on, derive a subset of left edge samples and a subset of top edge samples, and apply an affine model to the subset of left edge samples and the subset of top edge samples to generate a middle block of middle samples; , filter the intermediate samples to generate the final prediction block, and decode the current block of video data based on the final prediction block.
