| Abstract: | The XYZ coding strategy and statistical characteristics of 3DDCT coefficients have been deeplystusied 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. |
