摘要：
A new coding scheme for lossy-to-lossless compression of volumetric data using three-dimensional packet wavelet transform is presented. The need of unitary transform via the integer lifting scheme and the performance comparison of different integer filter kernels is discussed. A state-of-the-art coder, Set Partitioning In Hierarchical Trees (SPIHT), is considered and modified in order to adapt its tree-structure to the 3D packet wavelet structure defined. The algorithm is extensively tested and shows very good performance, both for lossy and lossless coding.
