Abstract
Systems and methods for content-adaptive segmented prediction mode are provided. A method includes receiving a coded picture and reconstructing a current block of the coded picture. The reconstructing includes: segmenting samples of the current block into a plurality of segments including a first segment and a second segment; predicting the first segment of the current block of the coded picture by using a first prediction mode; and predicting the second segment of the current block of the coded picture by using a second prediction mode, different from the first prediction mode.
Claims18
A method performed by at least one processor, the method comprising:
- receiving a coded picture;
- and
- reconstructing a current block of the coded picture, the reconstructing comprising:
- segmenting samples within the current block into a plurality of segments including a first segment and a second segment;
- predicting the first segment of the current block of the coded picture by using a first prediction mode that is an intra block copy (IBC) mode;
- and
- predicting the second segment of the current block of the coded picture by using a second prediction mode, different from the first prediction mode, that is an intra prediction mode that uses neighboring reconstructed samples to perform intra prediction.
A system comprising:
- at least one memory configured to store computer program code;
- and
- at least one processor configured to access the computer program code and operate as instructed by the computer program code, the computer program code comprising:
- reconstructing code configured to cause the at least one processor to reconstruct a current block of a coded picture that is received, the reconstructing code comprising:
- current block segmenting code configured to cause the at least one processor to segment samples within the current block into a plurality of segments including a first segment and a second segment;
- first prediction code configured to cause the at least one processor to predict the first segment of the current block of the coded picture by using a first prediction mode that is an intra block copy (IBC) mode;
- and
- second prediction code configured to cause the at least one processor to predict the second segment of the current block of the coded picture by using a second prediction mode, different from the first prediction mode, that is an intra prediction mode that uses neighboring reconstructed samples to perform intra prediction.
A non-transitory computer-readable medium storing computer instructions that are configured to, when executed by at least one processor, cause the at least one processor to:
- reconstruct a current block of a coded picture that is received by:
- segmenting samples within the current block into a plurality of segments including a first segment and a second segment;
- predict the first segment of the current block of the coded picture by using a first prediction mode that is an intra block copy (IBC) mode;
- and
- predict the second segment of the current block of the coded picture by using a second prediction mode, different from the first prediction mode, that is an intra prediction mode that uses neighboring reconstructed samples to perform intra prediction.
