基于小波变换的多尺度SAR图像比对

Multi-scales SAR image comparison based on wavelet transform features

提出一种基于小波变换在多尺度条件下用特征匹配进行SAR图像比对的方法,针对不同时间所采集的同一区域的SAR图像,自动快速地确定感兴趣的区域(ROI)并作出标识。实验结果表明,该方法能准确地进行SAR图像比对和ROI标识,具有实际应用价值。

This article developed a Synthetic Aperture Radar （SAR） image comparison method based on multi-scales wavelet transform by means of feature matching.This method will identify the Region of Interest （ROI） automatically and quickly for the SAR images of same region collected at different time.The experimental data indicates that this method can perform accurately SAR image comparison and ROI identification which has huge practical value.
