LAND COVER CLASSIFICATION USING E-SAR POLARIMETRIC DATA
Land cover Polarization Detection SAR Accuracy Theory Test
2015/7/29
Different decomposition approaches have been proposed in order to analyse and interpret SAR polarimetric images. These are based
either on the complex voltage reflection matrix, like Pauli, or on po...
根据无人机(UAV)景象匹配导航的现实需求,对具有典型人造场景的机载合成孔径雷达(SAR)图像与可见光图像,提出一种基于直线特征的SAR图像与可见光图像配准方法。首先,利用改进的直线段检测(LSD)方法提取图像直线特征;其次,构造控制线并设计了一种基于控制线的图像配准方法;最后,依据仿射变换模型实现了待配准图像的精确自动配准。实验表明,在SAR和可见光图像存在较大灰度差异、旋转和平移的情况下,该算...
