Abstract
Method and apparatus for hierarchical bi-directional intra-prediction in a video encoder is described. In some examples, initial reference blocks are selected in an image. Sets of blocks in the image are predicted successively over a plurality of stages based on a respectively plurality of templates, each of the plurality of templates including reference blocks selected from at least one of: the initial reference blocks; or previously encoded and reconstructed blocks of the image. The image is encoded in the video encoder using the initial reference blocks and the sets of blocks as predicted.
