IMAGE ENCODING DEVICE AND IMAGE DECODING DEVICE USING TRIANGULAR PREDICTION MODE, AND IMAGE ENCODING METHOD AND IMAGE DECODING METHOD PERFORMED THEREBY - A simplified explanation of the abstract
This abstract first appeared for US patent application 18353962 titled 'IMAGE ENCODING DEVICE AND IMAGE DECODING DEVICE USING TRIANGULAR PREDICTION MODE, AND IMAGE ENCODING METHOD AND IMAGE DECODING METHOD PERFORMED THEREBY
Simplified Explanation
The patent application describes an image decoding method that involves decoding information related to a triangle prediction mode for a current block from a bitstream. The current block is then split into two triangular partitions based on this information.
- The method includes generating a merge list for the triangle prediction mode using a regular merge mode.
- A motion vector is selected for the two triangular partitions based on information indicating the motion vector from motion vectors included in the merge list.
- Prediction blocks corresponding to the two triangular partitions are obtained from a reference image using the selected motion vector.
- Finally, the current block is reconstructed based on a final prediction block.
Original Abstract Submitted
An image decoding method including: obtaining, from a bitstream, information related to a triangle prediction mode for a current block; splitting the current block into two triangular partitions, according to the information related to a triangle prediction mode; generating a merge list for a triangle prediction mode, according to a merge list generation method in a regular merge mode; selecting a motion vector for the two triangular partitions according to information indicating the motion vector from among motion vectors included in the merge list; obtaining, from a reference image, prediction blocks corresponding to the two triangular partitions, based on the motion vector; and reconstructing the current block, based on a final prediction block.
