提出了一种利用小波多尺度分解的显著特征与熵相结合的图像融合算法,将其作为合成孔径雷达图像与其他源图像融合合成规则。局域显著特征体现图像变化的幅度,局域熵体现了图像局域信息量,理论分析和实际处理表明,该算法提高了融合图像信息的完整性,融合图像中目标更易于识别。

In this paper,a new images fusion approach of SAR and other source images has been proposed.A kind of area-based significance feature and area-based entropy selection operatior has been designed to adapt to the characteristics of the multiresolution wavelet coefficients.The theoretical analysis and practice show that the algorithm improves the description ability of fusion image and make the edge information more integral.
