Abstract
Multi-view video coding technique has been widely applied to 3D stereoscopic
display. This paper proposes a rate control algorithm for multi-view video
codec which is a tradeoff method between the data compression ratio and picture
quality of 3D video. This study utilizes the characteristics of visual perception
for 3D video viewers to determine the interesting regions in all view videos.
Interesting regions with different levels, which depend on the existence of
macroblocks with high motion, objects with individual shape, or obvious texture,
are determined in the proposed algorithm by considering the corresponding
Just Noticeable Distortion function, luminance histogram bin variation and
edge strength, respectively. Then the proposed algorithm assigns adequate
quantization parameters to control the bit-rate for different levels of interesting
regions such that the video quality of the interesting regions is preserved
and the bit-rate in the non-interesting regions is reallocated to 3D video
storage and transmission for stereoscopic display. The experiment results
show that the proposed method successfully achieves high quality preservation
and low bit-rate for 3D effects.
