多光谱图像信息量的研究

A RESEARCH ON INFORMATION AMOUNT OFMULTISPECTRAL IMAGES

本文以信息论为基础，研究了多光谱图像各波段的相关性及最佳波段组合，提出了合理利用多光谱图像的方法。对武汉地区SPOT（11月份）和TM（9月份）的多光谱图像分析结果表明：对于SPOT的三个波段，以波段1-3为最佳的两波段组合。对于TM的六个波段（第6波段除外），以波段3-4-5为最佳的三波段组合。

: This paper investigates the correlation and the optimum combination of bands of multispectral images on the basis of information theory. A method of rational use of multispectral images is presented. The results of analysis of SPOT and TM images of Wuhan area show that a combination of bands 1-3 is optimum for three SPOT bands, and the bands 3-4-5 are the optimum combination for six TM bands (except for the band 6).
