Adaptive difference domain space and temporal reference reconstruction and smoothing

摘要

An apparatus for coding video information according to certain aspects includes a memory unit and a processor in communication with the memory unit. The memory unit stores difference video information associated with a difference video layer of pixel information derived from a difference between an enhancement layer and a corresponding base layer of the video information. The processor determines an enhancement layer weight and a base layer weight, and determines a value of a current video unit based on the difference video layer, a value of a video unit in the enhancement layer weighted by the enhancement layer weight, and a value of a video unit in the base layer weighted by the base layer weight.
