| 摘 要： | 高分辨率图像是人们一直追求的目标,超分辨率图像重建技术就是人们获取高分辨率图像的一种很重要的方法。研究了超分辨率贝叶斯方法,该方法利用全波段增强多光谱遥感影像,结合传感器特性模拟了全波段和多波段影像的观测过程。这种方法使全波段数据与多光谱波段数据自动对齐,成功地保留了光谱信息,实现了遥感数据信息的高保真,进而增强了空间分辨率。以IKONOS全波段和多波段影像为例进行了深入地探讨,并对自动融合的结果进行了定性和定量分析。

| Abstract: | Acquisition of high resolution images is the goal for which people are always seeking.The technology for rebuilding high resolution image is an important method for getting high resolution images.In this paper a new super resolution Bayesian method for rebuilding multispectral images which incorporates sensor characteristics to model the observation process of both panchromatic and the multispectral images.This method auto-align panchromatic and the multispectral data,keep the spectrum successfully,and enhance special resolution,enrich ground-info.Take IKONOS panchromatic and the multispectral images for instance to deeply investigate,and qualitative and quantitative analysis result of fusion. |
