Abstract
A method of an inter prediction process performed by a processing unit of a coding system comprises deriving combined linear combination parameters from two sets of linear combination parameters, where a first set of linear combination parameters is independent from the position of the to-be-predicted block and a second set of linear combination parameters depends on the position of the to-be-predicted block; and obtaining the value of the to-be-predicted sample using the combined linear combination parameters and predicted values of at least two samples belonging to different reference blocks of the to-be-predicted block.

A method for inter prediction implemented by a processor of a coding system, wherein the method comprises:
- deriving combined linear combination parameters from a first set of linear combination parameters and a second set of linear combination parameters, wherein the first set comprises at least one first parameter, wherein values of the first set are independent of a position of a to-be-predicted sample within a to-be-predicted block, wherein the second set comprises at least one second parameter, wherein values of the second set depend upon the position;
- and
- obtaining a value of the to-be-predicted sample using the combined linear combination parameters and predicted values of at least two samples of different reference blocks of the to-be-predicted block.
A coding device comprising:
- a memory configured to store one or more computer programs comprising instructions;
- and
- a processor coupled to the memory and configured to execute the one or more computer programs that when executed by the processor cause the coding device to:
- derive combined linear combination parameters from a first set of linear combination parameters and a second set of linear combination parameters, wherein the first set comprises at least one first parameter, wherein values of the first set are independent of a position of a to-be-predicted sample within a to-be-predicted block, wherein the second set comprises at least one second parameter, and wherein values of the second set depend upon the position of the to-be-predicted sample within the to-be-predicted block;
- and
- obtain a value of the to-be-predicted sample using the combined linear combination parameters and predicted values of at least two samples of different reference blocks of the to-be-predicted block.
A non-transitory computer-readable storage medium comprising computer-executable instructions stored thereon that when executed by a processor of a coding device, cause the coding device to:
- derive combined linear combination parameters from a first set of linear combination parameters and a second set of linear combination parameters, wherein the first set comprises at least one first parameter, wherein values of the first set are independent from a position of a to-be-predicted sample within a to-be-predicted block, wherein the second set comprises at least one second parameter, and wherein values of the second set depend upon the position of the to-be-predicted sample within the to-be-predicted block;
- and
- obtain a value of the to-be-predicted sample using the combined linear combination parameters and predicted values of at least two samples of different reference blocks of the to-be-predicted block.
