ENCODER-SIDE DECISIONS FOR BLOCK FLIPPING AND SKIP MODE IN INTRA BLOCK COPY PREDICTION

摘要

Innovations in the area of encoding blocks using hash-based block matching improve coding efficiency in many situations. For example, some of the innovations relate to encoder-side decisions about when to use block flipping during prediction. Other innovations relate to encoder-side decisions about when to use skip mode for a block predicted using intra block copy (“BC”) prediction.
