摘要
详细研究了XYZ编码策略及3DDCT系数的统计特性,提出改进的XYZ变长编码策略,新的编码方法符合3DDCT系数分布特点,提高了编码效率。
The XYZ coding strategy and statistical characteristics of 3DDCT coefficients have been deeply
stusied in this paper. A modified varied length XYZ coding strategy is proposed, which matches the distri-
bution characteristics of 3DDCT coefficients and can increase the coding efficiency.
