Title:
INNOVATIONS IN BLOCK VECTOR PREDICTION AND ESTIMATION OF RECONSTRUCTED SAMPLE VALUES WITHIN AN OVERLAP AREA
Document Type and Number:
WIPO Patent Application WO/2015/102975
Kind Code:
A3
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 estimation of sample values within an overlap area of a current block during block vector estimation. Other innovations relate to prediction of block vector ("BV") values during encoding or decoding using "ping-pong" approaches.
