1. An apparatus for video decoding, comprising one or more processors, wherein the one or more processors are configured to:
obtain a sample value for a first pixel based on a motion vector (MV) for a current sub-block, a MV for a sub-block that is adjacent to the current sub-block, and a sample value for a second pixel that is adjacent to the first pixel, wherein the first pixel is a boundary pixel of the current sub-block; and
decode a block comprising the current sub-block based on the obtained sample value for the first pixel.
