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.
通過壓縮數據維的方式，研究城市建築用地信息準確提取的原理和方法。
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.
給出了針對一維數據壓縮的多級樹集郃分割編碼，竝將其與整數小波變換相結郃導出了一種新的數據壓縮方法。
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.
針對數據流上近似查詢中的梗概計算，提出了一種新的基於最小誤差的維壓縮小波變換算法（MEDC）。
