Abstract
This application provides an example inter prediction method and a related example apparatus. One example method includes parsing a bitstream to determine prediction information of a to-be-processed picture block, where the prediction information indicates that a prediction direction of the to-be-processed picture block is bidirectional prediction, where the bitstream does not include target identification information, and where the target identification information indicates to perform local illumination compensation (LIC) on the to-be-processed picture block; and obtaining a prediction value of the to-be-processed picture block based on the prediction information.
Claims20
An inter prediction method, wherein the method comprises:
- parsing a bitstream to determine prediction information of a to-be-processed picture block, wherein when the prediction information indicates that a prediction direction of the to-be-processed picture block is bidirectional prediction, the bitstream does not comprise target identification information, and wherein the target identification information indicates to perform local illumination compensation (LIC) on the to-be-processed picture block;
- obtaining a prediction value of the to-be-processed picture block based on the prediction information;
- parsing a second bitstream to determine second prediction information of a second to-be-processed picture block, wherein when the second prediction information indicates that a prediction direction of the second to-be-processed picture block is unidirectional prediction, the second bitstream comprises second target identification information, and wherein the second target identification information indicates to perform the LIC on the second to-be-processed picture block;
- and
- obtaining a prediction value of the second to-be-processed picture block based on the second prediction information.
A decoding apparatus, comprising:
- at least one processor;
- a non-transitory computer-readable storage medium coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions instruct the at least one processor to:
- obtain a bitstream;
- parse the bitstream to determine prediction information of a to-be-processed picture block, wherein when the prediction information indicates that a prediction mode of the to-be-processed picture block is inter prediction and a prediction direction of the to-be-processed picture block is bidirectional prediction, the bitstream does not comprise target identification information, and wherein the target identification information indicates to perform local illumination compensation (LIC) on the to-be-processed picture block;
- obtain a prediction value of the to-be-processed picture block based on the prediction information;
- obtain a second bitstream;
- parse the second bitstream to determine second prediction information of a second to-be-processed picture block, wherein when the second prediction information indicates that a prediction direction of the second to-be-processed picture block is unidirectional prediction, the second bitstream comprises second target identification information, and wherein the second target identification information indicates to perform the LIC on the second to-be-processed picture block;
- and
- obtain a prediction value of the second to-be-processed picture block based on the second prediction information.
