Abstract
A video processing method includes receiving a reconstructed frame, and applying in-loop filtering, by at least one in-loop filter, to the reconstructed frame. The step of in-loop filtering includes performing a sample adaptive offset (SAO) filtering operation. The step of performing the SAO filtering operation includes keeping a value of a current pixel unchanged by blocking the SAO filtering operation of the current pixel included in the reconstructed frame from being applied across a virtual boundary defined in the reconstructed frame.
