EFFICIENT MODE DECISION METHOD FOR MULTIVIEW VIDEO CODING

摘要

A method for determining a macroblock (MB) coding mode for a current MB in a dependent view. A window around a co-located MB in a base view is determined, wherein the co-located MB is a MB in the base view having a same location as the current MB in the dependent view. A coding mode complexity value (CMCV) is determined for each MB in the window, wherein the CMCV is based on a coding mode used to encode the MB. Rate distortion optimization (RDO) is performed for the current MB using a reduced number of coding modes if a total CMCV for all MBs in the window is less than a threshold, or using all supported coding modes if the total CMCV for all MBs in the window is greater than the threshold. A coding mode for the current MB is determined based on the RDO results.

1. A method for determining a macroblock (MB) coding mode for a current MB in a dependent view, comprising:
determining a window around a co-located MB in a base view, wherein the co-located MB is a MB in the base view having a same location as the current MB in the dependent view; selecting a motion vector (MV) of a MB in the window that is close to the co-located MB as a candidate MV; calculating an average MV of all candidate MVs in the window; performing rate distortion optimization (RDO) for the current MB using a reduced number of coding modes if a difference between the MV of the co-located MB and the average MB is greater than or equal to a threshold; performing RDO for the current MB using all supported coding modes if the difference between the MV of the co-located MB and the average MB is less than the threshold; and determining a coding mode for the current MB based on the RDO results.
