Enhancement layer scan order derivation for scalable video coding

摘要

An apparatus for coding video information includes a memory unit configured to store video information associated with a reference block; and a processor in communication with the memory unit, wherein the processor is configured to determine a value of a current video unit associated with the reference block based on, at least in part, a classification of the reference block and a scan order selected by the processor based upon the classification. The scan order indicates an order in which values within the reference block are processed to at least partially determine the value of the current video unit.

1. An apparatus for coding video information, comprising:
a memory configured to store video information associated with a reference block; and a processor in communication with the memory, wherein the processor is configured to:
determine a classification of the reference block based upon a horizontal texture strength and a vertical texture strength associated with the reference block, wherein the horizontal texture strength and the vertical texture strength are determined as a function of a difference between adjacent pixel values within the reference block;select a scan order of a current video unit associated with the reference block based upon the determined classification; anddetermine a value of the current video unit based on, at least in part, the selected scan order,wherein the scan order indicates an order in which values within the reference block are processed to at least partially determine the value of the current video unit.
