It ' s the aim for many pepole to improve the image resolution . one of the proper approaches to the aim is the siginal processing based methods in software . it can recover the high resolution image from multiframe undersampled images 提高遙感影像的分辨率一直是人們追求的目標(biāo),實(shí)現(xiàn)這一目標(biāo)的有效途徑之一便是采用基于信號(hào)處理的軟件方法,其基本原理是應(yīng)用同一地區(qū)多幅重復(fù)觀測影像之間的互補(bǔ)信息,用超分辨率重建算法恢復(fù)高分辨率圖像。
