| 摘 要： | 基于Radarsat-2全极化SAR、GF-1多光谱、Landsat-8多光谱影像,利用PCA变换、HSV变换等方法,分析了同空间分辨率的SAR与光学全色影像的信息量,并评价了其分别与Landsat-8多光谱影像的融合结果。结果表明:全极化SAR影像较全色影像的亮度高,图像标准差、信息熵及平均梯度总体趋于一致,信息量相当;融合影像目视效果相近,且SAR融合影像较光学融合影像包含的信息量更为丰富,利用高分全极化SAR影像替代光学全色影像开展海岸带遥感监测是可行的。

| Abstract: | In this paper,based on Radarsat-2 full-polarization SAR,GF-1 multispectral and Landsat-8 multispectral images,we analyze the information content of the SAR and panchromatic images with the same spatial resolution,and evaluate results respectively fused with Landsat-8 multispectral image,using PCA and HSV method.The results show that the brightness of polarization SAR images is higher than panchromatic images.The standard deviation,information entropy,average gradient and amount of information tend to be consistent.Fusion images have similar visual effects,and the SAR fusion image contains more information than the optical fusion image.So the use of high polarization SAR images instead of optical panchromatic image in the coastal remote sensing monitoring is feasible. |
