摘要
基于影像匹配一致性，结合小波变换与分析，提出了一种适用于遥感影像的有失真压缩编码方法。考察了不同的压缩倍率对影像匹配偏移中误差的影响。
A compression method of keeping match consistency on remote sensing image is represented. A lot of results of experiments are presented. The results describe the relation between image compression and match. At the same time, conclusion is drawn that for aerial remote sensing image at 25 μm resolution, when the compression ratio is 8∶1,match consistency is kept.
