Abstract
The present disclosure relates to storage of motion information for affine mode. A video processing method is provided, including: selecting, during a current affine calculation step in a conversion between a current block and a bitstream representation of the current block, one or more parameters of a set of affine model parameters; storing the one or more parameters for the current block; and performing, based on the one or more parameters, the conversion between the current block and the bitstream representation of the current block.
Claims20
A method of processing vide data, comprising:
- selecting, during a current affine calculation step in a conversion between a current block and a bitstream of the current block, one or more parameters of a set of affine model parameters;
- storing the one or more parameters for the current block;
- and
- performing, based on the one or more parameters, the conversion between the current block and the bitstream of the current block.
An apparatus for processing video data comprising a processor and a non-transitory memory with instructions thereon, wherein the instructions upon execution by the processor, cause the processor to:
- select, during a current affine calculation step in a conversion between a current block and a bitstream of the current block, one or more parameters of a set of affine model parameters;
- store the one or more parameters for the current block;
- and
- perform, based on the one or more parameters, the conversion between the current block and the bitstream of the current block.
A non-transitory computer-readable recording medium storing a bitstream of a video which is generated by a method performed by a video processing apparatus, wherein the method comprises:
- selecting, during a current affine calculation step in a conversion between a current block and a bitstream of the current block, one or more parameters of a set of affine model parameters;
- storing the one or more parameters for the current block;
- and
- generating the bitstream based on the one or more parameters.
