Change Detection in SAR Image Based on Multisacle Product and PCA

摘要：

In this paper,we present a new method of change detection in SAR images based on multiscale product of wavelet transform and PCA algorithm. This method applied multiscale product of wavelet transform,in order to avoid the affect of speckle noise in sAR,enhance the changed information and weaken the effect of noise. The algorithm of PCA is used to merge every scale after the process of multiscale product. To show the effectiveness of the proposed technique,experiments are conducted on two SAR datasets.Results are compared with two methods which based on wavelet transform and PCA,and it is proved to be superior.
