Abstract
A method comprising obtaining (601) at least one characteristic of a current sample of a picture before reconstructing the current sample; determining (602) parameters of a film grain synthesis process to be applied to the current sample from the at least one characteristic; storing (603) the determined parameters with information representative of a location of the current sample; reconstructing (604) the current sample; and, applying (605) the film grain synthesis process on the current sample with the determined parameters.
Claims18
A method for decoding comprising:
- obtaining at least one characteristic of a current block comprising a current sample of a picture before a prediction to obtain the current block has started;
- determining parameters of a film grain synthesis process to be applied to the current sample from the at least one characteristic;
- storing the determined parameters with information representative of a location of the current sample;
- reconstructing the current sample;
- and,
- applying the film grain synthesis process on the current sample with the determined parameters.
