METHOD AND APPARATUS FOR INTRA-PREDICTION IN A VIDEO ENCODER

摘要

Method and apparatus for intra-prediction in a video encoder are described. An aspect relates to a method of intra-prediction for a group of samples in an image being coded. In some examples, the method includes: defining a target template for the group of samples; comparing the target template with affine transformations of candidate templates within a search area of the image; identifying at least one matching template of the candidate templates as matching the target template; determining a candidate group of samples based on the at least one matching template; and coding the group of samples using the candidate group of samples as a predictor.
