data dimension compression

基本解释

Based on a data dimension compression technique, this paper studies the principles and method of remote sensing information extraction for urban built up land.
通过压缩数据维的方式，研究城市建筑用地信息准确提取的原理和方法。
A set partitioning in hierarchical trees encoder for one dimension data was developed. A novel compression method was proposed by combining the encoder with integer wavelet transform.
给出了针对一维数据压缩的多级树集合分割编码，并将其与整数小波变换相结合导出了一种新的数据压缩方法。
Aiming at synopsis computation of approximate query in data stream, a novel wavelet transformation algorithm, Minimum Error based Dimension Compression (MEDC) algorithm, is proposed in this paper.
针对数据流上近似查询中的梗概计算，提出了一种新的基于最小误差的维压缩小波变换算法（MEDC）。
