Encoder-side options for intra block copy prediction mode for video and image coding

Abstract:

Innovations in encoder-side options for intra block copy ("BC") prediction mode facilitate intra BC prediction that is more effective in terms of rate-distortion performance and/or computational efficiency of encoding. For example, some of the innovations relate to concurrently performing block vector ("BV") estimation and making block splitting decisions for a block. Other innovations relate to selectively merging blocks into a larger block during BV estimation.
