  • Publication number: 20230171421
    Abstract: For a bi-prediction block, the initial motion field can be refined using a DNN. In one implementation, the initial motion field is integer rounded to obtain initial prediction blocks. Based on the initial prediction, the DNN can generate motion refinement information, which is scaled and added to the sub-pel residual motion from the initial motion field to generate a refined motion field. The scaling factor can take a default value, or be based on the motion asymmetry. While the initial motion field is usually block based on sub-block based, the refined motion field is pixel based or sub-block based and can be at an arbitrary accuracy. The same refinement process is performed at both the encoder and decoder, and thus the motion refinement information need not to be signaled. Whether the refinement is enabled can be determined based on the initial motion, the block activities and the block size.
