Abstract
Multiview Video Coding contains a macroblock-based illumination compensation tool which can compensate the variations of illuminations according to view or temporal directions. Thanks to illumination compensation tool, the coding efficiency of Multiview Video Coding has been enhanced. However illumination compensation tool also generates additional subjective drawbacks of the blocking artifacts due to macroblock-based compensations of mean values. A deblocking filtering method for Multiview Video Coding which is the same as in H.264/AVC does not consider illumination difference between the illumination compensated blocks, thus it can not effectively eliminate the blocking artifacts. Therefore, this paper analyzes the phenomena of blocking artifacts caused by illumination compensation and proposes a method which can effectively eliminate the blocking artifacts with the minimum changes of the H.264 deblockding filtering method. In the simulation results, it can be easily found the blocking artifacts are clearly eliminated in the subjective comparisons, and the average bit-rate reduction is up to 1.44%.
