| 摘 要： | 指出了基于像素灰度值的影像表征方法在表达检测目标信息上的不足,提出了运用小波变换的方法对遥感影像进行信息提取和表达。为了增强表达检测目标信息的能力,采用H aar母小波作为影像小波变换的小波基。实验表明:基于小波变换的表征方法在遥感影像目标检测的诸多性能指标上都优于基于影像像素灰度值的表征方法。

| Abstract: | At present time,representation method based on image pixel grey is used to expressing the information of the detected object,but it is deficient.In this paper,a new method using wavelet transform is put forward to withdraw with and express information of the remote sensing images.In order to build up the ability of expression,Haar mother wavelet is adopted to wavelet transform.Result shows that the representation method based on wavelet transform is superior to that based on image pixel grey in many functionalities of object detection for the remote sensing images. |
