中文摘要：

为了对多波段SAR图像进行有效的融合,提出了一种基于非子采样Contourlet变换的多波段SAR图像伪彩色融合方法。该方法首先对多波段SAR图像进行基于亮度的波段选择,按选择方法将图像分别赋予R、G、B通道;所得RGB图像通过IHS变换得到亮度分量I;再利用非子采样Contourlet变换对I分量和另一波段图像进行多尺度分解,低频和高频图像分别采用活性测度和绝对值最大规则进行系数选择;最后将融合结果与H、S分量进行IHS反变换,得到新的RGB图像。实验结果表明,采用该方法进行多波段SAR图像伪彩色融合是可行和有效的。

This paper proposed a multi-SAR image fusion method based on the nonsubsampled Contourlet transform to fuse multi-band SAR images effectively.Firstly,selected multi-band image based on image bright.With band-selection for R,G,B color space,acquired and transformed RGB image by intensity-hue-saturation(IHS) transform.Decomposed the intensity component and another band SAR image by the nonsubsampled Contourlet transform with same scales and directions.Merged the lowpass subbands and the directional high-frequ...
