Local illumination compensation (LIC) for virtual pipeline data units (VPDUS)

Abstract:

Techniques are described herein for processing video data. For instance, a current block of a picture of the video data can be obtained, and it can be determined that the current block includes more than one virtual pipeline data unit (VPDU). Current neighbor samples for the current block, reference neighbor samples for the current block, and additional neighbor samples for the current block can be obtained for illumination compensation. One or more illumination compensation parameters can be determined for the current block using the current neighbor samples, the reference neighbor samples, and the additional neighbor samples. The additional neighbor samples are used for determining the one or more illumination compensation parameters based on the current block covering more than one VPDU. Illumination compensation can be performed for the current block using the one or more illumination compensation parameters.
