本文针对西部干燥荒漠地区的地貌地表影像,进行了基于信息量的波段选取和融合试验,获取了一定的经验值,将此经验值应用于相似类型地表的影像融合后,取得了良好的效果。经实际生产作业证明,基于信息量理论选取的组合波段,能很好地保持原始影像的光谱特征,且融合后,影像层次丰富、色彩逼真。
In this paper, according to the geomorphological images of the dry desert in the western region, a band selection and fusion experiment based on the information volume is carried out, and some empirical values are obtained. After this empirical value is applied to image fusion of similar types of surface, good results have been obtained. After the actual production operation proves, the combination band selected based on the theory of information quantity can well maintain the spectral characteristics of the original image, and after the fusion, the images are rich in levels and vivid in color.
