摘要: 提出一种改进的三维等级树集分割编码算法。该算法针对三维等级树集算法对纹理复杂、边缘较多的图像编码效率低,存储空间和时间开销大等缺点进行了改进。经试验证明,改进后的三维等级树集分割编码算法提高了压缩效率,节约存储空间和时间开销,降低扫描编码复杂度,无方块效应,具有较好的性能。

Abstract: This paper introduces an improved 3D-SPIHT algorithm. This algorithm can deal with the problems such as low efficiency when coding pictures with complex textures or many-sided pictures, large storage requirement and long time consumption, which are common to traditional 3D-SPIHT algorithm. The test shows that improved 3D-SPIHT algorithm can increase the compress ratio, save storage and time consumption, reduce the complexity of scanning codes. This algorithm avoids diamond effect and has a good performance.
