摘要
遥感影像数据融合是影像处理的一项重要内容。本文在分析已有的影像融合方法的基础上 ,提供了边缘叠加遥感影像数据融合法 ,并以绍兴市郊IRS、SPOT和ETM卫星影像为资料进行试验 ,通过具体的统计分析将该方法融合的影像与其他方法融合的影像进行了比较分析研究。
Data fusion on remote sensing images is an important i tem in image data processing.This paper introduces a remote sensing image data f usion meuhod with edge added by wavelet transformation,and chooses IRS,SPOT and ETM images as the experimental datum.Through the statistical analysis in which t his method has been compared with the other ones based on wavelet transformation ,the results show that the image fusion method presented in this paper is quite feasible.
