| 摘 要： | 合成孔径雷达(Synthetic Aperture Radar,简称SAR)图像受到斑点噪声影响以及成像条件的变化,使得同一场景的两幅SAR图像之间存在很大差异,利用基于边缘特征或灰度信息进行SAR图像配准,难以达到预期效果.基于此,本文提出一种基于分割区域的SAR图像配准方法,该方法首先利用主动轮廓方法对去噪后的SA...

| Abstract: | Due to the speckle imaging and the impact of the different conditions,the synthetic aperture radar(SAR) images may differ considerably under the same scene.However,using the method of the gray or edge feature,the results of SAR image registration may not be ameliorated.Therefore,we propose a method based on the segmentation-derived region to register the SAR image.After denoising the SAR images,the segmentation regions can firstly be obtained by using the active contour image segmentation.Moreover,we extrac... |
