Abstract:
The present disclosure provides systems and methods for processing video data. A method includes: performing a decoder side motion vector refinement (DMVR) process to generate a bi-predicted signal, wherein performing the DMVR process comprises: determining a refined motion vector for a target coding unit, without using wrap-around motion compensation; determining whether the wrap-around motion compensation is enabled; and in response to a determination that the wrap-around motion compensation is enabled, generating, based on the refined motion vector, a bi-predicted signal using the wrap-around motion compensation.
