| 摘 要： | 为提高极化合成孔径雷达图像相干斑抑制的效果,提出基于核独立成分分析(kernel independent component analysis,KICA)的极化SAR图像相干斑抑制方法.该方法将三个通道的极化信息作为输入数据,经过KICA变换得到三个独立分量,取相干斑指数最小的分量作为滤波后的信息图像.由于将核函数引入...

| Abstract: | In order to improve the accuracy of polarimetric synthetic aperture radar image speckle reduction,a polarimetric SAR image speckle reduction method using kernel independent component analysis(KICA) is presented.This method uses the polarimetric information of three channels as its input data,obtains three independent components after KICA conversion,and takes the one with the smallest speckle index as the filtered results.Due to the introduction of kernel function,the information that can not be linearly se... |
