• significant wavelet coefficients - 引用次数：5

  Block-based wavelet transform is applied to large-scale volume data, and effective octree structure is constructed to store significant wavelet coefficients map. The algorithm is not only a better compression ratio but it’s easy to random access block-based data.

  通过对大规模体数据进行基于块的层次小波分解和构造有效的八叉树结构来保存小波重要系数位置信息,该算法不仅有较好的压缩率,而且很容易进行基于数据块的随机访问。
