干涉条纹图噪声的滤除是InSAR数据处理的关键步骤之一。针对干涉条纹图的各向异性特征,提出一种基于条纹中心线的InSAR干涉图滤波算法,考虑到干涉条纹中心线获取的复杂性,此算法采用细胞神经网络快速提取干涉条纹图的条纹中心线。通过用真实的InSAR干涉图实验证明此方法具有很好的滤波效果,滤波结果视觉特征良好、残余点减少,保持了图像的边缘和细节特征,而且降低了为滤波效果所付出的时间代价。

Removing the noise of the interference-stripes images is one important step during the data processing of InSAR.Aimed at the anisotropic characteristic,a method for InSAR interferogram filtering method based on the center lines of the interference-stripes is proposed.Considering the difficulty to obtain the center lines of the stripes,the algorithm proposed in this paper extracts the center lines of interference-stripes quickly by using CNN(Cellular Neural Networks) algorithm for its parallel feature to pro...
