摘要
为了综合合成孔径雷达(SAR)与红外成像这2种探测手段各自的优点,提高侦察效果,运用剪切波变换工具,提出一种能充分保留原SAR与红外图像边缘特征的融合策略。算法利用了剪切波对多曲线图像多分辨表示的优势,通过梯度取大的融合策略保留了原SAR与红外图像中的边缘信息。实验结果表明,该算法能有效抑制斑点噪声干扰,保留原图像边缘信息,是一种有效的SAR与红外图像融合方法。
To integrate the advantages of Synthetic Aperture Radar(SAR) and infrared imaging and improve the reconnaissance effect,this paper applies shearlet transform tool and propose a fusion strategy to fully maintain the margin features of SAR and infrared imaging.Taking advantage of shearlet in representing images containing edges in multi-resolution,the algorithm can retain the edge information of original images with the gradient maximin strategy.The numerical experiments demonstrate that the proposed algorithm can effectively suppress speckle noise,and retain the original edge information,which is an effective method for SAR and infrared image fusion.
